Page 14: Installation
Locate the serial number labels on the power supply and verify the model number, the input voltage rating and the output voltage rating and polarity. In the event of any damage promptly notify the transportation company and the TDK-Lambda Americas Inc. customer service manager. -
Page 15: Power Cord Specification
Never handle the HV cable during operation. Always use the HV connector and cable provided with the power supply or an equivalent substitute provided by TDK-Lambda Americas Inc. Fully insert the connector end of the HV cable and tighten the locking nut only "hand tight". -
Page 16: Grounding The Product
Keep the minimum HV cable bend radius greater than 4" (101.6mm) to minimize stress on the insulation. Keep the HV cable as distant as possible from the input power and the input control signals. To connect the HV cable to the load it is necessary to remove the cable jacket, shield, and any semiconducting layer that remains on the cable insulation after removing the shield. -

Page 18: Operation
4 OPERATION 4.1 L, S, OEM MODELS Model LC1202L: This model has full front panel instrumentation for use in laboratory, prototype or OEM systems. The LC1202L can be operated either from the front panel or from the rear panel remote control connector. The front panel includes power on/off, remote/local and HV on/off switches, output voltage adjust, view set switch, digital volt- age and current meters, quick reference bar graphs and status indicators. -
Page 19: Rear Panel
Model LC1202 OEM: This model has a blank front panel and is operated the same as an LC1202S, from the remote control connector only. It can function as a stand alone unit or in parallel for increased output power. The basic model LC1202 OEM is supplied by ex- ternally controlled AC power. -
Page 20: Front Panel Control (L Model Only)
Figure 8 Rear Panel 4.3 FRONT PANEL CONTROL (L MODEL ONLY) 4.3.1 POWER SWITCH: Connects AC input power to the control circuitry and closes the internal AC contac- tor if the interlock is closed. 4.3.2 CONTROL SWITCH: Directs the power supply to take on/off and voltage program commands from ei- ther the front panel (LOCAL position) or the remote control connector (REMOTE position). -
Page 21: Remote Control (L, S, Oem Models)
4.4 REMOTE CONTROL (L, S, OEM MODELS) All three models are easily controlled through their remote connector on the rear of the unit. Only the HV ON/OFF, V PROGRAM and GND signals are required for operation. The remaining signals are provided for status monitoring and fault diagnosis. A sche- matic diagram showing the suggested interface circuit appears after the following de- scription of control signals. - Page 22 Active Logic level (low) to be between 2 and 4V. If an external pullup resistor is added, the Active Logic level (low) voltage will be higher. For LC1202-OEM models, a pullup resistor is required to sense voltage levels at these outputs.

17. Assert ON/OFF signal to 15V. 18. Verify HV output is at approx. zero volts. 19. Increase HV output slowly and verify adjustability. LC1202 OEM Remote Control: 20. V PROGRAM signal (pin 22) at zero volts. 21. ON/OFF signal (pin 8) at zero volts. -
Page 25: Applications
5 APPLICATIONS 5.1 DETERMINING CAPACITOR CHARGE TIME The LC1202 Series is rated at 13500 J/sec peak and 12000 J/sec average charge rate. Although the measure of Joules/sec equates to Watts, it is more convenient when work- ing with energy storage capacitors. The peak charge rate determines the capacitor charge time. -
Page 26: Paralleling Units
R E P R A T E 5.3 PARALLELING UNITS The LC1202 power supply is designed for simple parallel operation. Any model (L, S, OEM) can be paralleled with any other model. The input power and HV output should be connected directly together. -
Page 27: Determining Ac Line Current
5.6 OPERATION AS A DC POWER SUPPLY The LC1202 can provide a regulated voltage to a DC load such as an electron beam. The output current will be preset at the factory in order to limit the average output power to 12000W, while making full rated HV steady state. -
Page 28: Maintenance And Troubleshooting
If the power supply is making high voltage but does not appear to be functioning properly in a specific application, the problem may be application related. Consult the TDK-Lambda Americas Inc. customer service department. If the power supply is not making high voltage, the problem is usually either failed HV output diodes or a problem on a pc board. - Page 29 Check the V PROGRAM input at U1-12.

Page 30: Input Voltage Conversion Procedure
7 INPUT VOLTAGE CONVERSION PROCEDURE 7.1 OVERVIEW The 1202 power supply was designed so that the input line voltage can be easily changed from 208VAC to a 400VAC (and vice versa) in the field by technically quali- fied person. Each supply will be shipped configured to the voltage shown on the input label on the rear panel of the supply. -

b) For fuse PCB assembly Rev. E or higher, use kits 12494004 or 12494005. Three fuses need to be replaced for the conversion. These fuses are all located on the fuse assembly (Fig 14). Replace the fuses F4, F5, and F6 are 60A for the 208VAC and 30A for the 400VAC supply. -
