Protection is provided for overcurrent and overvoltage fault conditions. Operation of the Power Supply This Power Supply module can operate from either 120 VAC or 240 VAC nominal inputs. It will also operate from a nominal 125 VDC source. The specified range of operation is from 90 VAC to 264 VAC, and from 100 VDC to 150 VDC. For continuous operation (greater than one hour) at low line voltages and high temperatures, some power derating must be applied. Refer to the following figure to determine the normal operating range for specific applications. Normal operating range is shown by the shaded area of the graph for 60 C (140 F) installations. Operation in the non-shaded region for specific applications must be limited to <1 hour. Reducing the maximum operating temperature to 55 C (131 F) will increase the normal operating range as indicated on the graph. Active power factor correction circuits in this supply maintain a near unity power factor for AC inputs, which eliminates the need for oversized circuit breakers and wiring. This circuitry also limits the half cycle peak inrush currents to a low value. 55 C 60 C 50 C 90 100 110 120 130 100 95 90 85 LIMITED OPERATING RANGE (< 1 HOUR ) 264 MAXIMUM TOTAL OUTPUT POWER (WATTS) INPUT VOLTAGE (VRMS OR VDC) NORMAL OPERATING RANGE FOR CONTINUOUS OPERATION (>1 HOUR) IN MINIMUM SIZE ENCLOSURE WITH NO FORCED AIR CIRCULATION. VIN 95 105 Figure 1. Power Derating for Low Line Voltages Overvoltage Protection An electronic shutdown circuit protects against voltages exceeding 6.2 volts. A back-up voltage clamp is provided to protect against sustained overvoltage conditions due to either external influences or internal faults. Overvoltage due to internal faults may cause the fuse to open. For short term overvoltage conditions, normal operation will resume when the cause is removed. Overcurrent Protection An electronic current limit is provided on each of the three outputs. An overload on any output will cause the voltage to collapse and may cause the other output voltages to collapse. Normal operation will resume after removal of the overload. Some component cooling time may be required before normal operation resumes. 3 Power Supply Module, 100W, 120/240 VAC or 125 VDC GFK-1448B Power Supplies August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 10-3 Dual Rack Operation A single power supply can provide power for two racks under the following conditions: 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 in close proximity as limited by the available 3-foot connecting cable. The connecting cable used for dual rack operation is listed in Table 2, Ordering Information. This cable carries the +5 volts 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. Inter-rack communication and bus interface modules must be provided separately. See the applicable Programmable Controller Installation Manual. for application information. FACE TWO RACK POWER CABLE INSTALL CABLE SO THAT THE INDICATED END IS SUPPLYING POWER Figure 2. Dual Rack Configuration Timing Diagram The timing diagram below shows the relationship of the ac input power to the dc outputs and to the two system signals generated by the power supply: ACFAIL and SYSRESET. The 5VSTBY output may be used for user battery backup schemes as shown. On application of power, the ACFAIL signal goes false soon after the 5 volt bus is within specification. The system is held in the Reset state by SYSRESET for at least 200 milliseconds after 5 volt power is available (during this time, outputs are forced off). If AC input power is interrupted, the 5 volt bus will remain within specifications for at least one cycle. The system is then given an additional 5 milliseconds to complete an orderly shutdown before SYSRESET stops all processing. 5ms MIN 21 ms MIN 200 ms MIN OUTPUT 4.9V 4.9V POWER SYSRESET ACFAIL 26.5ms MIN 1 CYCLE INPUT POWER ON AC OFF ON OFF 5VSTBY 2 1 2 1 5VSTBY CONNECTED TO POWER SUPPLY 5VDC 2 5VSTBY DISCONNECTED FROM POWER SUPPLY 5VDC BY A TRANSISTOR TO ALLOW CONNECTION OF USER BATTERY SOURCE. a42132 50ms MIN | } Figure 3. Timing Diagram Note Input power interruptions which exceed the power supply holdup time (21 milliseconds minimum) will result in a complete power down/power up cycle of ACFAIL and SYSRESET. Mounting This Power Supply is a plug-in module that is installed in the leftmost slot of any standard IC697 rack or VME Integrator s rack.

Use care when opening the door since pulling from the bottom can cause the hinge or the door to break. Field Wiring Connections The power input terminal board has four terminals. The top two (L1 and N) are for 120/240 VAC or 125 VDC input power connections; the third and fourth terminals are for ground and overvoltage protection device connections, respectively. Power input connections should be made with copper AWG #16 (1.3 mm2 ) wire rated for 75 C (167 F). Each terminal can accept solid or stranded wires, but the wires into any given terminal should be the same type and size. It is recommended that the ground terminal on the power supply be connected to the GND terminal on the rack and to earth using copper AWG #12 (3.3 mm2 ) wire rated for 75 C (167 F) to ensure adequate grounding. Use of a nut and star washer for each wire on the ground terminal is recommended.

H N G Figure 4. Terminal Board Connections for IC697PWR711/713, Versions H and Later Overvoltage Protection Devices The overvoltage protection devices (see Figure 5) for this power supply are connected internally to terminal 4 (bottom terminal) on the input terminal board. This pin is normally connected to frame ground (terminal 3) with the supplied jumper strap which is installed at the factory. If overvoltage protection is not required or is supplied upstream, this feature can be disabled by leaving terminal 4 unconnected by removing the jumper strap. If you want to Hi-pot test this supply, overvoltage protection must be disabled during the test by removing the terminal board strap. Re-enable overvoltage protection after testing by reinstalling the strap. 1 2 3 4 a47106 Jumper Strap Connects Overvoltage Protection Devices to Frame Ground Screw Terminals on Terminal Board Frame Ground Figure 5. Overvoltage Protection Devices and Jumper System Noise Immunity Two easy steps must be taken to properly ground the programmable controller system to reduce the possibility of errors due to electrical noise (see Figure 5). 1. The Ground terminal on the power supply must be connected to the GND terminal on either side of the rack using AWG #12 (3.3 mm2 ) wire. The Ground terminal should be also be connected to incoming safety ground. 2. The GND terminal on the rack must be connected to a good earth ground. 5 Power Supply Module, 100W, 120/240 VAC or 125 VDC GFK-1448B Power Supplies August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 10-5 Table 1.
