PAN35-20A(MODEL 700W)/MODEL 1000W In the case of the PAN35-20A and the models 1000W, securely con- nect the (GND) wire of the power cable to the ground terminal on the switchboard.
Chapter 2 Before Using the Unit Before using the unit, users are requested to thoroughly understand the following matters. Inrush current An inrush current may flow when the POWER switch is turned on. See Table 2-1. If you are planning to use several sets of the unit in a system, and to turn on the POWER switches at the same time, check that the AC power source or the switchboard is of sufficient capacity.
Output terminals on the front panel The output terminals on the front panel are auxiliary output terminals. These terminals, however, may not satisfy the given specifications of the unit. The PAN16-50A has no output terminals on the front panel. Load Note that the output may become unstable when one of the following loads is connected.
2.4.2 When a load generates a reverse current to the power supply The unit cannot absorb a reverse current from a regenerative load such as an inverter, converter or transformer that supplies current to a power supply. Consequently, the output voltage will increase and the output will fluctuate.
2.4.3 In case of load with accumulated energy, such as batteries Connecting a load with accumulated energy, such as a battery, to the output of the unit may cause a large current to flow from the load through the internal output control circuit protection diode to the internal capacitor.
CV power supply and CC power supply The unit is capable of both constant voltage and constant current operation. This section describes these operations. The ideal constant voltage power supply has zero output impedance at all frequencies and maintains a definite constant output voltage with respect to variations in load current.
Page 38
■ Connecting a 10 Ω resistive load A resistive load of 10 Ω is connected to the output terminals of the power supply and the output current limit is set to 5 A. In this condi- tion, output voltage is raised gradually from 0 V. In this case, the power supply operates in the constant voltage (CV) mode.
Page 39
■ Connecting a 25 Ω resistive load We consider a case of using a load resistance of 25 Ω. In this case, when the output current limit is set to 4 A or more, the power supply is capable of outputting voltages from 0 V to the rated maximum out- put voltage while in constant voltage operation mode.
Output Terminal Isolation • Be sure to securely connect the output terminal to WARNING the chassis terminal using the short bar provided. Possible electric shock may lead to death or injury. • For safety reasons, even if the output terminal is CAUTION grounded, make sure the insulation capacity of the output terminal (including the sensing terminal) is...
Page 41
■ When the output terminal is not grounded The cable and load that are connected to the output terminal (includ- ing the sensor terminal) must have an insulation capacity that is greater than the isolation voltage of the power supply with respect to the chassis.
Page 42
■ When the negative output terminal is connected to the chassis terminal As shown in Fig.2-9, the negative output terminal will be at ground potential. Consequently, the cable and load that are connected to the output terminal (including the sensor terminal) must have an insula- tion capacity that is greater than the maximum output voltage of the power supply with respect to the chassis.

Presetting the OVP trip point • After presetting the OVP trip point, be sure to check CAUTION that the OVP function works at the preset voltage (Procedure 4 to 6). For checking, it is necessary to output an actual voltage. Therefore, first check that no load is connected, and proceed with the following procedure.
3.2.2 Using as a constant voltage power supply • For safety, turn off the POWER switch when connect- WARNING ing the load. 1. Check that the OUTPUT switch is turned off. 2. Turn on the POWER switch. 3. While pressing the LIMIT switch, preset the requested cur- rent by turning the CURRENT control knob.

Mounting the auxiliary output terminal cover The unit is provided with a front auxiliary output terminal cover. Mount the cover when the unit is to be used. The PAN16-50A has no auxiliary output terminals on the front panel. • The output electrode on the auxiliary output terminal WARNING is uncovered.

Chapter 4 Applied Operation Use of the CONTROL terminal board on the rear panel allows the unit to perform remote sensing, external output control, parallel oper- ation, and series operation. • To avoid electric shock, for remote sensing lines and WARNING control lines, use wires with a rated voltage higher than the isolation voltage of the unit.

3. Use a wire stripper to remove the covering from wires. Remove the covering from each wire over a distance of 7 mm to 10 mm (9 mm is recommended). Use of the strip gauge on the top or rear panel of the unit, or that shown in Fig.4-2, allows you to remove the required amount of covering from a wire.
Remote sensing The remote sensing function is intended to reduce the influence of voltage drops affected by the load cable resistance, to keep the output voltage stable at the load terminal. To perform remote sensing, an electrolytic capacitor that has good frequency characteristics is needed at the sensing point (load terminal).
Page 66
• For sensing wires, use wires with a higher voltage WARNING rating than the isolation voltage of the unit. For details, see "2.6 Output Terminal Isolation". Protect the uncovered section of the shielded wire by using insulation tubes with a withstand voltage greater than the isolation voltage of the unit.

Analog remote control It is possible to remotely control the unit's output voltage and current using analog signals. Output ON/OFF operation by means of external contact points is also possible. The above-mentioned remote of controls can be used in combination, but note the following exceptions.
Page 71
■ Before performing analog remote control The unit is factory-adjusted for control from the front panel (i.e., local control). Before using remote control (excluding output ON/OFF using external contact points), re-adjustment is necessary. Re-adjust- ment is also necessary when changing from remote control back to local control.

Master-slave-control parallel operation It is possible to increase the current capacity by connecting a maxi- mum two slave units in parallel to one master unit. In a master-slave- control parallel operation system, the output preset for all the units connected in parallel can be provided only on the master unit. To perform such master-slave-control parallel operation, an electro- lytic capacitor should be connected to the load terminals.
Connection and setup procedure 1. Turn off the OUTPUT switch of each unit. 2. Turn off the POWER switch of each unit. 3. Determine the master unit. NOTE • If the PAN-A and PAN series are used together, assign the PAN-A series power supply as the master unit.
Page 88
• Use a load cable of sufficient current capacity to WARNING cover the rated value. • After parallel connection, mount the output terminal cover (on the front or rear panel). To mount the front auxiliary output terminal cover, see "3.4 Mounting the auxiliary output terminal cover".
Page 89
7. Connect an electrolytic capacitor (C) with a capacity of a few hundreds of μF to a few tens of thousands of μF to the load terminals as necessary. • Use a capacitor (C) whose withstand voltage is 120 CAUTION % or more of the unit's rated voltage.
