The PFC version connection is shown in Figure 3-2. Connect the input voltage line wires to L2 and COM terminals. WARNING: 152A and 202A PFC Models are only available with 220 VAC Nominal. For 152A Models Suffix 110 at 110-120 VAC must be operated with the internal fuses F1 and F2 (on the Inverter Board) replaced by copper bus provided with the supply. - Page 15 The currents developed with voltage reversal at high rep. rates, could damage the power supply. A resistor in series with the HV output can be added to limit this current to an acceptable level. Refer to Section 5.2, Page 15 for more information.

Page 16: Grounding Of Input Line
3.6.1 GROUNDING OF INPUT LINE The supply is grounded through the ground terminal of the input connector. A protective ground connection by the way of the grounding conductor in the input terminal is essential for safe operation. 3.6.2 OUTPUT GROUND CONNECTION It is important that there be a ground connecting the supply to the load as shown in Figure 3-3. - Page 17 4 - 1 DESCRIPTION INPUT A high signal (+10 to 15V) with respect to ground (pin 14) will enable the power supply. Latching faults can be cleared by cycling this switch. Ground or open disables the supply. INPUT A 0-10V signal with respect to ground at this pin programs the output voltage proportionally from zero to rated output.

FAULT. If there is a short circuit or overload condition on the output, the power supply will operate in a 50% duty cycle protection mode and indicate a LOAD FAULT. -

The peak charge rate determines the capacitor charge time. The average charge rate determines the total power delivered from the power supply. It is possible to charge a capacitor at 1650 J/sec, but to discharge it at a low rep. rate producing an average of 100 J/sec. -
Page 21: Figure 5.2 Output Current Measurement
Sometimes when operating several units in parallel, the high total power generates noise which interferes with the power supply control. This is usually due to the many interconnecting control cables acting as an antenna picking up noise. The problem usually appears as one or more of the power supplies shuts down when the output voltage increases beyond a certain level. - Page 22 When making a DC measurement, such as when the power supply is holding voltage on a capacitor, any HV probe and DVM combination can be used. The Fluke 80K-40 probe with any 10M input resistance DVM is adequate up to 40kV. Building a simple resistor divider using appropriate HV resistors is also very straightforward.

Page 23: Applications
When charging very large capacitor banks requiring many seconds or minutes to reach end-of-charge, the power supply will display a load fault and go into a 50% duty cycle protection mode. If this feature is defeated and the power supply is allowed to charge for an extended period, the peak output power, not the average power, must be used to determine line current. -

(e.g., power transistors readily explode during fault conditions). Because the power supply does not receive proper cooling with the cover removed, it must be cooled by an external fan placed next to the supply to cool the inverter and HV section (min.
