Functional Description

IS200JPDBG1ABA is an AC power distribution module developed by GE. It is part of the Mark VIe series. The AC Power Distribution Module serves the purpose of conditioning, monitoring, and distributing AC power within a system. The module features two separate AC distribution circuits, each capable of handling 20 amperes (20A) at either 115 or 230-volt AC. These circuits are designed to manage and distribute power efficiently within the specified voltage and current ratings.

Features

• Wiring Configuration for Input Circuits: It's recommended to wire the input circuits in parallel to avoid PPDA (Power Diagnostic Alarm) occurrences when a single source of AC power is provided. This parallel configuration ensures an uninterrupted power supply and prevents alarm triggers due to a single source failure.
• Branch Circuit Outputs: For each circuit, the module provides one fused and three fused-and-switched branch circuit outputs. These outputs offer options for controlled power distribution and management within the system.
• Optional Connection 125V DC Distribution Module: The module allows for connection to an optional JPDF 125V DC Distribution Module, facilitating integration and distribution of DC power as needed within the system.
• Monitoring and Status Feedback: The board, integrated into the module, includes passive monitoring circuits for AC magnitudes and status feedback for all fused circuits. Connector P1 is utilized for these monitoring circuits, which are compatible with cable connections to a board containing a power diagnostic PPDA I/O pack.
• Connector P2 for Monitoring Signal Pass-Through: Connector P2 allows for the pass-through of monitoring signals from other power distribution system cards, enhancing the monitoring capabilities and ensuring comprehensive system oversight.
• Flexibility in Configuration: Two modules can be cabled into a single PPDA I/O pack when required, offering flexibility in system configuration and scalability as per system demands.
• AC Source Selector Integration: The module provides an additional connector specifically designed for systems requiring an AC source selector. This connector intercepts the two AC sources supplied, directing them to the JSS1 connector on the board edge. The output of the AC selector is then wired to JSS1, distributing power to individual branch circuit outputs as needed.
• Circuit Breakers: It's important to note that the basic module does not include circuit breakers. However, options exist to provide circuit breakers on a mounting plate that fastens to the sheet metal support. Specific job-related documentation should be referred to for information regarding any circuit breakers attached to the JPDB.
• In essence, the module is a versatile and configurable unit designed for efficient AC power management, distribution, and monitoring within a system, offering various options for power distribution, monitoring, and integration with other components as required.

Installation

• Mounting Configuration: The module is vertically base-mounted onto a metal back base within the cabinet typically utilized by the Power Distribution Module (PDM). This secure mounting ensures stability and proper positioning within the system.
• Establishing Ground Connection: To maintain system safety and integrity, a connection between the sheet metal and the system's Protective Earth is essential. This grounding connection serves to protect the module and the system from potential electrical hazards.
• Input Power Connection: Input power is applied to designated terminals for each AC circuit. For the first AC circuit, power is connected to terminals AC1H (line) and AC1N (neutral). Similarly, for the second AC circuit, power connections are made to terminals AC2H (line) and AC2N (neutral). It's crucial that both AC inputs have grounded neutral connections for safety and compliance with electrical standards.
• Output Circuit Connections: Output circuits are connected as per the documentation provided for the specific system configuration. Proper documentation and adherence to guidelines ensure accurate and efficient distribution of power to the intended components or devices within the system.
• Integration with PPDA Power Diagnostic I/O Pack: In systems equipped with a PPDA power diagnostic I/O pack, a 50-pin ribbon cable is required to establish a connection between JPDB connector P1 and the P2 connector located on the board holding the PPDA. This connection allows for communication and signal transfer between the module and the power diagnostic I/O pack. It's acceptable for this connection to pass through other core PDM boards utilizing the P2 connector, allowing for a streamlined integration of the power diagnostic functions within the system architecture.

Grounding

• In Mark VIe systems, grounding plays a crucial role in ensuring both safety and functional reliability. The grounding framework is divided into two distinct categories: Protective Earth (PE) and Functional Earth (FE). The PE ground is primarily designed to protect personnel and equipment from electrical faults, requiring a connection to an appropriate earth that complies with local electrical safety standards and regulations. This grounding system must be capable of carrying a minimum of 60 amperes for at least 60 seconds without exceeding a voltage drop of 10 volts. Such specifications are vital for ensuring that, in the event of a fault, the ground can effectively dissipate fault currents while maintaining safety.
• Conversely, the FE ground is utilized for the proper functioning of electronic equipment and must be bonded to the PE ground at a single point. This bonding is essential in preventing ground loops, which can introduce noise and compromise system performance. The Joint Power Distribution Board (JPDB) is grounded through metal mounting supports that securely attach to the underlying sheet metal of the module.
• The grounding is applied to the metal switch bodies on the JPDB, ensuring that all components of the board share a common ground potential. Moreover, the ground serves as a local reference point for generating feedback signals on connector P2. An important design feature is that the sheet metal of the module is insulated from the mounting surface, allowing the JPDB ground to be defined independently of that surface. Typically, mounted at a lower position within the cabinet, and a dedicated ground wire connects the JPDB module to the PE. The length of this ground wire is critical, as it minimizes impedance at radio frequencies, which is essential for the effective functioning of input line filters and for preventing interference that could disrupt system performance.

Physical Arrangement

• The physical arrangement of components in a Mark VIe system is vital for maintaining optimal performance and simplifying wiring complexity. When an optional power source is employed alongside, the selector switch should be positioned directly above.
• This strategic placement facilitates a short power connection between the two components through the JSS1 connector, thereby reducing potential voltage drops and enhancing power delivery efficiency. In scenarios involving a JPDF (125 V dc) board, the JAF1 connector supplies the necessary alternating current (AC) power to the JPDF. To further minimize wiring lengths and improve overall efficiency, it is advisable to position the JPDF directly below.
• Effective cable management is also a key consideration in the design of the JPDB. The ribbon cable headers, P1 and P2, on all boards are thoughtfully positioned to optimize cable routing. The JPDS or JPDM, which houses the PPDA I/O pack, is best located at the top of the board arrangement. This layout allows ribbon cables to flow seamlessly from one card to the next, with cables exiting the top of one card and entering the bottom of the subsequent card until they reach the PPDA host.
• Connector P1 is responsible for transmitting feedback signals to the board hosting the PPDA I/O pack, ensuring real-time data availability for system monitoring and control. In contrast, connector P2 receives feedback from other power distribution boards, enabling the passage of signals out of P1 to the PPDA. This well-structured approach to signal routing is essential for minimizing the risk of signal degradation and interference, thereby supporting the overall reliability and performance of the system. Through meticulous attention to grounding and physical arrangement, Mark VIe systems are designed to operate effectively within their intended applications.
