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.
