What It Takes to Keep Regulated DC Power Supply Stable Part 1: Connecting Cable

What It Takes to Keep Regulated DC Power Supply Stable Part 1: Connecting Cable

A regulated DC power supply (referred as DC power supply) is an electrical device to convert AC into a constant DC. Its function is to maintain a constant output voltage, however, unfortunately even if you use an intelligent DC power supply, improper wiring can mess up a whole system operation or performance. In this white paper, we explain the best practices for connecting a power cable and load...

Switching Function Improvement in PLZ5W Series

PLZ5W Series features a switching current function to repetitively fluctuate between two current levels, and this function has been improved as compared with the previous model of PLZ4W Series for the following characteristics: 1) Switching speed 2) Switching waveform quality * In PLZ4W Series, the switching speed tends to become slow when connecting a resistance load. Here you will find th...

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...

Operation Tutorial to Perform Simulated CC Operation in PCR-LE Series

1. Overview In PCR-LE Series, simulated CC operation can be achieved by setting the current limit in AC mode. This method is based on its internal system as the ammeter monitors the output current and the arithmetic circuit controls the output voltage. The functions and characteristics of thi...
