Output Connection Methods with Parallel Control

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...

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...
