    LEDs. The "S" Models have been designed to operate as a slave unit to the "L" Models or in systems where local control is not a requirement. As many 203 or 303 supplies as required, can be connected in parallel to provide greater output power.

  • Page 8: Capacitor Charging Technology

    The flexible design of the 203 and 303 allow the units to be ordered with (L model) or without (S model) the front panel controls and meters. The front panel controls are ideal in applications where local control and readbacks are necessary, such as R&D, labora-...

  • Page 9: Safety Precautions

    Please take care to refer to the correct information for your unit. SAFETY PRECAUTIONS All 203 and 303 power supplies are designed to mini- mize the risk of fire or shock hazard. This instrument received comprehensive mechanical and electrical in- spection prior to shipment.

    1. With AC power OFF and disconnected, connect an appropriate load capacitor to the power supply output cable. 2. Prepare to charge the capacitor. NOTE: Operating a 203 or 303 power supply into an open circuit (no load operation) will instantly damage the power supply's H.V.

  • Page 18: Contacting Tdk-Lambda Americas Customer Service

    The supply and the coolant filled HV assembly should not be opened unless advised by TDK-Lambda Americas personnel. The coolant filled HV tank has been cleaned and the hermetically sealed at the factory, opening the supply or the assembly will void the facto- ry warranty, and may compromise performance.

  • Page 19: Installation

    Never install the 203 or 303 so only the front panel screws support its weight! The 203/303 must never be installed without support in the back or sides of the unit. The 203/303 should be mounted on heavy-duty chassis slides –such as General Devices CTS-124- or on a suitable shelf or supports inside the rack.

  • Page 20: Ventilation Requirements

    TB 1 AC INPUT 3.5” (89mm) Figure 4-2 203/303 Rear View VENTILATION REQUIREMENTS Ensure there is at least 5 inches (12.5 cm) of clearance at the rear of the unit for air- flow, cables and water lines. If the power supply is to be installed in an enclosed system, care must be taken to ensure the ambient inlet air to the power supply does not exceed the maximum operating temperature of 55°C.

  • Page 21: Ac Power Connection

    TDK-Lambda Americas standard warranty. The customer’s AC power line connects to the 203/303 via a UL/CSA approved 5 posi- tion terminal block on the rear panel of the unit (see Figure 4-3). Only use a power cable with the correct voltage and current rating (see Table 4-1).

  • Page 22: Connecting The High Voltage Output

    Always use the HV connector and cable provided with the power supply or an equivalent substitute provided by TDK-Lambda Americas. Fully insert the connector end of the HV cable and tighten the locking nut only "hand tight". When operating above 20kV and 200Hz rep rate a silicone grease (such as Dow Corn- ing DC-4) must be applied to the HV cable before insertion into the HV connector.

  • Page 23: Figure 4-4 Typical Load Circuit Connection

    Generally, a resistor in series with the HV output can be added to limit this current to an acceptable level. Refer to Application Note 517 (available from the factory or at www.us.tdk-lambda.com/hp) for more information. COOLANT WATER COOLANT WATER COOLANT WATER...

    An L model supply can simulate an S model with the key in the REMOTE position. 5.10 POWER SUPPLY STATUS LEDs (Ref 9) There are four distinct sets of status LEDs on the 203/303L/S front panel. Each group indicates the status of a specific section of the power supply. 5.10.1 STATUS LED GROUP 5.10.1.1...

  • Page 29: Autoinhibit (Normally Off)

    CONTROLS, INDICATORS, CONNECTORS 5.10.1.3 AUTOINHIBIT (Normally OFF) The AUTOINHIBIT feature shuts OFF or inhibits the output current when the capacitive load is discharged. This feature allows the HV switch in the external load circuit (if appli- cable) to better recover after a load switching event. The AUTOINHIBIT feature overcomes the need for the external inhibit signal in most cases.

    5.10.3 COOLANT LED GROUP In the event of any coolant faults the user should verify installation orientation is in ac- cordance with Section 4.4 prior to contacting TDK-Lambda Americas. 5.10.3.1 FULL (Normally ON) When illuminated, this indicator signals that the high voltage tank in filled to the correct level with coolant.

  • Page 31: Purge Valve (Normally Off)

    CONTROLS, INDICATORS, CONNECTORS The coolant has a wide operating temperature range and is controlled and stabilized by the cooling water flowing through the high voltage tank. The maximum allowable tank temperature is 45°C, and the minimum is 15°C. This temperature range can be maintained by running normal tap water through the power supply at a rate of 2 gallons per minute (7.58 L/min).

  • Page 39: Operating Instructions

    7-15 OPERATING INSTRUCTIONS The 203/303 power supply is designed for operation in two modes. The first mode is lo- cal, where the power supply is operated using the front panel controls. Local operation is only possible with the L model supply. The second mode is remote, where control sig- nals are passed via the 25pin remote connector.

  • Page 40: Remote Operation (All Models)

    For a full explanation of each control and indicator refer to Section 5. REMOTE OPERATION (All models) All 203/303 models are easily controlled through the 25 pin sub D-type remote interface connector located on the rear panel. The minimum required signals for remote control operation are;...

  • Page 41: Remote Control Signals

    To operate an L model in remote mode the front panel keyswitch must be in the REMOTE position. Before operating either a 203/303L or S in remote mode it must first be connected to a master supply, or an appropriate control system.

  • Page 43: Remote Operation With Inhibit

    Although the AUTOINHIBIT signal offers the user the simplest remote programming method for the 203/303, the INHIBIT signal is commonly used to control the output cur- rent and offers greater flexibility, allowing the user to minimize the time at which the load capacitor remains at high voltage.

  • Page 44: Parallel Operation

    HV output cables together at the load. Either model 203/303L or 203/303S or any combination of units can be operated in parallel. If at least one model 203/303L is connected in a parallel system then the system can be operated without an external controller by using the 203/303L as a master supply in local mode.

  • Page 45: Parallel System Comprising Both 203/303L And 203/303S Supplies

    Parallel system comprising both 203/303L and 203/303S supplies For a system comprising both 203/303L and S units, a single L model should be operat- ed as a master in either local or remote mode. The other parallel supplies can be con- nected to the SLAVE 25-pin D-sub connector on the master unit rear panel (refer to Fig- ure 7-4).
