72775.jpg WARNING

Risk of electric shock.

Do not touch the OUTPUT terminal block, the outlets, and the sensing terminal block.The time required for the internal capacitors to discharge when no load is connected is approximately 0.1 seconds.

In DC mode, even if the output is off, if a capacitor, battery, or similar item is connected as the load, a voltage remains in the device that is connected to the OUTPUT terminal block, the outlets, and the sensing terminal block until the load’s energy is discharged.

72764.jpg CAUTION

When you turn the output on, several volts of undershoot or overshoot may occur for several tens of microseconds.

Each time that you press OUTPUT, the output toggles between on and off.

Output on

“OUTPUT ON” is shown on the display.

A voltage and frequency that correspond to the output mode and output range that you have specified are generated.

Output off

“OUTPUT OFF” is shown on the display.

If a protection function is activated and the product is in the alarm state, the output is turned off.

power is turned on

You can select the state of the output when the POWER switch is turned on.

Press OTHERS (SHIFT+MEMORY), 1/2 (F6), and then PON OUTP(F4) to set the state of output.

The output is off when the power is turned on.

FORCE

The output is on when the power is turned on.

Impedance when the output is off

The internal circuits and the output of the PCR-LE2 Series are not separated by a mechanical switch or relay. The PCR-LE2 Series turns the output off by electrically increasing the output impedance. This enables you to turn the output on and off without chattering. When the output is off, the output is set to high impedance, and the output voltage is nearly 0 V.

Even when the output is on, the following impedances are present, so if the load is a battery or a similar device, a slight current may flow into the PCR-LE2 Series, and the load may be discharged.

Voltage surge suppression when the output is turned off

You can set the voltage surge suppression that is activated when the output is turned off.

When the output is off, the output of this product is at high impedance.

If voltage surge suppression is set to ON (factory default setting), immediately after the output is turned off, the output voltage is set to 0 V (low output impedance), and then the impedance is changed to high. To prevent large overshooting and undershooting by the load immediately after the output is turned off, we recommend that you use the PCR-LE2 Series with the voltage surge suppression set to on.

When voltage surge suppression is on, an unexpected current may flow through the product immediately after the output is turned off depending on the connected load (power conditioner, regenerative inverter, battery, etc.). This may affect the test. Turn voltage surge suppression off for the above loads.

Press CONFIG (SHIFT+OPR MODE), 1/2 (F6), and then SURGE S (F2) to set voltage surge suppression.

Surge suppression

Voltage surge suppression on

The output is turned off after the output voltage is set to 0 V.

OFF

Voltage surge suppression off

The output is turned off with the output left at high impedance.

Output on/off phase control

You can set the AC mode output on/off phase. You can set the output on and output off phases separately. This is valid in AC mode and AC+DC mode.

During single-phase, three-wire output and three-phase output, set the phase of the U-phase unit.
