Precautions When Operating AC Power Supply ‘PCR-LE Series’ in DC Mode

PCR-LE/LE2 Series can produce a DC output that enables you to test DC-powered devices

such as DC-input converters. This article introduces the important precautions and useful

functions to effectively operate PCR-LE/LE2 Series in DC mode.

1. Circuit Model

See Figure 1 for the test circuit model with PCR-LE. It illustrates the DC-input

converter/inverter that has a capacitor-input circuit but without an inrush current prevention

circuit.

2. Rated DC Current and Maximum Instantaneous Current

2-1 Rated DC Current for PCR6000LE

From Table 1;

DC input 200V: The rated DC current (maximum current) is 21A. The maximum

instantaneous current, 3.6 times the rated DC current, is 75.6A.

DC input 100V: the rated DC current is 42A. The maximum instantaneous current is 151.2A.

The rated DC current is 70% of the rated AC current.

From Figure 2;

Example 1) If DC input is 100V and the output voltage is

DC50V; the output voltage ratio is 50% → The output current

ratio is 100% → The output current equals the rated DC

current.

Example 2) If DC input is 200V and the output voltage is

DC400V; the output voltage ratio is 200% → The output

current is limited by 50% → The rated DC current is 10.5A

and the maximum instantaneous current is 37.8A.
