FUNCTIONAL DESCRIPTION:

IC695PSD040 is a 40-Watt DC Power Supply Module manufactured and designed by General Electric as part of the Mark II Series used in GE Speedtronic Control Systems. Power Supply is a 40-Watt supply that operates from an input voltage source in the range of 18 VDC to 30 VDC. This power supply provides three outputs:

• +24 VDC relay output that can be used to power circuits on Output Relay modules.
• +3.3 VDC. This output is used internally by RX3i modules with IC695 catalog numbers.

Power Supply version IC695PSD040 or before may cause equipment damage if inadvertently installed in the same backplane as another RX3i power supply. This DC Power Supply occupies one backplane slot. If the number of modules required exceeds the capacity of the Power Supply, the additional modules must be installed in Expansion or Remote backplanes, or power supplies capable of increased capacity mode operation must be used. The Power Supply indicates when an internal fault occurs so the CPU can detect loss of power or log the appropriate fault code.

LED OF POWER SUPPLY MODULE:

• Power (Green/Amber): When this LED is green, it indicates power is being supplied to the backplane. When this LED is amber, power is applied to the Power Supply, but the Power Supply switch is off.

• P/S Fault (Red): When this LED is lit, it indicates the Power Supply has failed and is no longer supplying sufficient voltage to the backplane.

• Over Temperature (Amber): When this LED is lit, it indicates the Power Supply is near or exceeding its maximum operating temperature.

• Overload (Amber): When this LED is lit, it indicates the Power Supply is near or exceeding its maximum output capability on at least one of its outputs.

OVERCURRENT PROTECTION:

The 5.1 VDC output is electronically limited to 7 Amps. The 3.3 VDC output is limited to 10 Amps. If an overload (including short circuits) occurs, it is sensed internally and the Power Supply shuts down. The Power Supply continually tries to restart until the overload condition is removed. An internal fuseable link in the input line is provided as a backup. The Power Supply usually shuts down before the fuse blows. The fuse also protects against internal supply faults. The CPU Fault Table shows a fault if any Overtemperature, Overload, or P/S Fault occurs. There is no additional indication if the Power Supply fuse blows.

INPUT OVERVOLTAGE PROTECTION:

The bottom terminal is normally connected to frame ground with a user-installed jumper, as shown at lower right. If overvoltage protection is not required or is supplied upstream, no jumper is required. To Hi-pot test this supply, overvoltage protection must be disabled during the test by removing the jumper. Re-enable overvoltage protection after testing by reinstalling the jumper. Each terminal accepts one AWG 14 to AWG 22 wire. The end of each wire should be stripped at least 3/8-inch (9mm). The terminal can accept a wire that is stripped up to 11 mm (.433 in) while providing full seating of the insulator. The wire must be fully inserted as shown at left, so that the insulation meets the insulation stop position inside the terminal. Tightening the terminal screw pivots the clamp firmly against the stripped end of the wire, holding it in place. If the wire is not fully inserted as shown at right, tightening the terminal screw may push the wire upward so that it is not connected.

FREQUENTLY ASKED QUESTIONS:

What is the input voltage range for this power supply?

The module operates from 18 to 30 VDC, with a nominal voltage of 24 VDC. It delivers stable output within this range, making it suitable for PACSystem RX3i applications. Voltages outside this range may trigger a fault or shutdown.

What outputs does the power supply provide?

It provides +24 VDC for external relay circuits and +3.3 VDC for internal module operation. These outputs ensure reliable power delivery to connected modules and system stability.

How much power can the supply provide?

The module delivers 40 Watts of DC power, adequate for standard RX3i modules and relay circuits. Exceeding this capacity will trigger overcurrent protection.

Can multiple modules be installed in the same backplane?

Earlier versions must not be installed alongside another power supply in the same backplane to prevent damage. For additional modules, use expansion or remote backplanes or higher-capacity supplies.
