SCR Controlled Emergency Light with Power Supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12915
Indian Lab Suppliers supplies the SCR Controlled Emergency Light with Power Supply (Product ID: 12915) as part of its electronics engineering lab equipment range. It is a working emergency light in which an SCR switches a battery-powered lamp on automatically when the mains fails.
Quick Answer
While mains is present, a 6 V, 2 A step-down transformer and four-diode bridge charge the on-board 6 V, 4 Ah battery and hold the SCR off. When the mains fails, the SCR receives gate current from the battery and switches the lamp on; restoring the mains returns the circuit to charging. The board is self-contained, weighs about 4 kg and runs from 230 V AC ±10%, 50 Hz. Do not short the battery terminals.
