FUNCTIONAL DESCRIPTION:

IC697PWR711 is a 125 VDC Programmable Controller Power Supply Module manufactured and designed by General Electric as part of the Mark II Series used in GE Speedtronic Control Systems. The 100-Watt Power Supply Module is a rack-mounted unit that plugs directly into a 48-pin backplane mounted connector in the leftmost slot in the rack. It provides +5 volt, +12 volt, and -12 volt power and logic level sequencing signals to the backplane. This power supply may be used either in a single rack application or may also be used to provide power to a second rack if the total load is within the supply rating. Interconnection to the second rack is through a prewired cable. The power supply output will ride through a one-cycle total loss of input power at full load. Protection is provided for overcurrent and overvoltage fault conditions.

FEATURES OF POWER SUPPLY MODULE:

• The power supply is versatile in input voltage, meaning it can operate on either 120-volt AC or 240-volt AC.
• The power supply provides three DC output voltages from a single AC input.
• Delivers up to +5 volts DC at 18 amps, which equals a maximum of 90 watts (5V × 18A).
• Provides a +12-volt DC output, typically used for analog components, motors, relays, or fan systems.
• Supplies -12 volts DC, often required for operational amplifiers, RS-232 serial ports, or analog systems needing symmetrical power.
• The module is designed for rack-mount systems, making it easy to install, remove, or replace without rewiring.
• This prevents damage to the power supply and connected components and may include automatic shutdown or current limiting.
• This feature allows one power supply module to power two racks, reducing cost and space.

OPERATION OF THE POWER SUPPLY:

This Power Supply Module can operate from a 120 or 240-volt nominal line (this is jumper selectable, as illustrated on page 3). For these two ranges, the power supply can accept an input voltage range of from 90 to 132 VAC or from 180 to 264 VAC, 47 to 63 Hz.

OVERVOLTAGE PROTECTION:

The power supply includes an electronic overvoltage protection circuit. This circuit will turn the output off if the 5-volt bus exceeds 6.2 +0.5 V. The power supply must be turned off to be reset. External overvoltage on the output that triggered the overvoltage protection will not cause the power supply fuse to open. However, if an internal fault in the power supply caused the overvoltage condition, the fuse may open. Replace this fuse with a 3AG 3 amp, 250-volt fuse.

OVERCURRENT PROTECTION:

The power supply provides electronic overcurrent protection for each of the 3 outputs. If the maximum current rating is exceeded, the voltage will collapse to a low value. It will remain in that state until the load is either removed or reduced. A current overload (including a short circuit condition) will not cause the fuse to open. This power supply does not comply with FCC requirements in non-industrial applications for conducted EMI on AC power lines.

DUAL RACK OPERATION:

• Only 5-volt power is required in the second rack, and the total power required by both racks is within the capability of the supply.
• The current drawn by the second rack is less than 5.2 amperes.
• The two racks must be mounted nearby as limited by the available 3-foot connecting cable.
• The connecting cable used for dual rack operation is listed in Table 1, Ordering Information. This cable carries the +5-volt power bus as well as the power sequencing signals.
• It uses a 9-pin D-type connector, which connects directly to the backplane through an opening in the rack frame. Note that the cable carries power and power sequencing signals only.

INPUT VOLTAGE GROUNDING:

The power input terminal board provides two points for connecting 120 VAC or 240 VAC power and two additional points that must be shorted together if the line voltage is 120 VAC and must be open if the line voltage is 240 VAC. Power input connections should be made with copper AWG #16 (1.33 mm2 ) wire rated for 75C (167F). Each terminal can accept solid or stranded wires, but the wires in any given terminal should be the same type and size.

FREQUENTLY ASKED QUESTIONS:

What is the input voltage range supported by the module?

Most 125 VDC power modules support a wide input range, such as 85–265 VAC or 110–250 VDC. This flexibility ensures compatibility with different power sources in industrial environments.

What is the output voltage accuracy and regulation?

Typical output voltage regulation is within ±1% of the rated 125 VDC. Load and line regulation ensure consistent output even with input fluctuations or varying load conditions.

What is the hold-up time during power loss?

Hold-up time typically ranges from 10 to 50 milliseconds, allowing connected controllers to shut down safely or switch to backup power during momentary outages.
