Output On/Off Behaviour of PBZ Series

For PBZ Series, a magnetic relay is used to turn the output on/off. The relay is off to turn the output off; when the output is off, the output is in the high impedance state. In addition, if the output-on/off is controlled by an external signal input, the embed...

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-i...

Output Connection Methods with Parallel Control

Parallel operation is very useful to expand an output capacity; especially master-slave parallel operation allows you to control an entire system by one master unit. When making the master-slave connection such as signal wiring and load connection, you may find some issues with load connection. Improper connection may cause oscillation so that our user’s manual describes how to connect the load...

PLZ Series Easy Way to Expand Electronic Load Capacity in CV Mode

PLZ Series Easy Way to Expand Electronic Load Capacity in CV Mode Our electronic load PLZ Series has a well-known feature that a master/slave parallel operation expands an output capacity in the same model, controlled slave units by a master unit (except for PLZ-4WL). In this article, we are going to further explain how to increase the capacity by parallel connection with d...

Using Electronic Load to Battery Charger Testing

Using Electronic Load to Battery Charger Testing A battery charger is a device that can recharge a secondary cell or rechargeable battery. Every battery charger being used requires the testing and such testing system must include something to simulate a battery. An electronic load can provide the best solution for the battery charger testing to simulate the actual behaviour o...
