Power Supplies GFK-1388A August 1997 1 9 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 9-1 120/240 VAC or 125 VDC, 55W Power Supply Module (IC697PWR710/712) datasheet GFK-1388A This data sheet (GFK-1388) describes version H (IC697PWR710H/712H), or later versions of this power supply. For a description of version G (IC697PWR710G/712G), and earlier versions see data sheet GFK-0083L. Features Operation from 120/240 VAC or 125 VDC Five volt DC output up to 11 amps Slide-in rack mount construction Electronic short circuit overcurrent protection provided on 5 volt bus Two rack operation from a single power supply Power factor corrected on AC inputs Jumper for overvoltage protection devices Functions This Power Supply Module for the programmable controller 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 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 an available prewired cable (see the ordering instructions on the last page of this data sheet). 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. GFK-1388A 120/240 VAC or 125 VDC, 55W Power Supply Module 2 Power Supplies August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 9-2 Operation of the Power Supply This Power Supply Module can operate from either a 120 VAC or 240 VAC nominal line. For these two ranges, the power supply can accept an input voltage range of from 90 to 264 VAC, 47 to 63 Hz. Active power factor correction circuits in this supply maintain a unity power factor which eliminates the need for oversized circuit breakers and wiring. This power supply will also operate with a 125 VDC nominal line. It will accept a DC input voltage range of 100 to 150 VDC. Overvoltage Protection The power supply includes an electronic overvoltage protection circuit. This circuit will clamp the output if the 5 volt bus exceeds 6.2 volts. External overvoltage on the output 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 1 amp, 250 volt 5x20 mm fuse. Overcurrent Protection The power supply provides an electronic overcurrent limit at 12 amperes, typical. If the maximum current rating is exceeded, the output voltage will drop. 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. 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 3-foot connecting cable. The connecting cable used for dual rack operation is listed in the ordering instructions. 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. Inter-rack communication and bus interface modules must be provided separately. See the applicable Programmable Controller Installation Manual for application information. FACE PLATE SECOND INPUT POWER ON OFF ON OFF AC Figure 2. Timing Diagram for Versions D and Later Note Input power interruptions which exceed the power supply ride through time (21 milliseconds minimum) will result in a complete power down/power up cycle of ACFAIL and SYSRESET. Mounting The Power Supply is a plug-in module that is installed in the leftmost slot of any standard IC697 rack or VME Integrator s rack. Power Supply Door The power supply door can easily be opened by grasping the upper left corner of the door with your right thumb or a fingernail and gently pulling the door towards you. 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.

Figure 3. Terminal Board Connections for IC697PWR710/712, Versions H and Later Overvoltage Protection Devices The overvoltage protection devices (see Figure 4) 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.

Re-enable overvoltage protection after testing by reinstalling the strap. Jumper Strap Connects Overvoltage Protection Devices to Frame Ground Screw Terminals on Terminal Board Frame Ground Figure 4. 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. 1. A 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. 2. The GND terminal on the rack must be connected to a good earth ground. Table 3.
