About This Product
This unit covers everyday needs such as basic electricity work, ray optics boxes and immersion heaters. Hex socket screws around the selector let a teacher or technician lock the voltage using the Allen key provided. The socket shrouds can be partly unscrewed to take bare wires. It has a captive mains lead with cable wraps on the back panel, and spare terminals and cable brackets are available. Besides buyers across India, the Basic PSU can be exported to institutions in Bahrain, Guyana, Nicaragua, Armenia, Palestine and Benin.
Frequently Asked Questions
Q1. Can the a.c. and d.c. outputs be used at the same time? No. Both come from the same sockets and are never live together, which stops students connecting the a.c. and d.c. outputs to each other.
