SCR CONTROLLED DC POWER SUPPLY
PS Series
Variable DC power supplies are AC to DC power supplies with a variable DC output. The output can be varied with an SCR controller. The AC input power can be single phase or three phases. With single phase AC input, the DC output ripple is very high (50%). With three phase AC input, the DC output ripple is low (5%). This would be a key benefit for selecting three phase AC input instead of single phase.

Earth Contact Resistance Tester
SCR ELEKTRONIKS have developed an equipment namely Earth Contact Resistance Tester to test the appliance. To ensure the safety of operator it is essential that the Earth path (connection) should offer minimum impedance to by pass short circuit Current to Earth. This is ensured by measuring Resistance of the Earth path by passing heavy Current say 25 A. The Earth Contact Resistance Tester essentially comprises of a Variable Current source with digital Ammeter to measure the Current supplied. The Voltage drop across the Earth path is measured with a digital Voltmeter. Optionally for a particular Current (25 A) the meter can be calibrated in terms of Resistance. A timer is provided to switch off the Current after the Set Time.

Calibration & Demag.
Model 8515-D
The Model 8515-D is a medium-energy, high voltage, and capacitor discharge type ringing demagnetizer capable of desaturating Ceramic and Rare Earth magnetic materials. The Model 8515-D is easily adapted to a wide range of production and laboratory demagnetizing requirements. A modern solid-state electronic control circuit, coupled with a rugged, heavy-duty discharge SCR and fixture, make this demagnetizer a highly reliable, low maintenance unit. The electronic voltage control circuit prevents the Model 8515-D from being discharged before the preset energy level has been reached, avoiding incomplete magnet desaturation. An easy to read front panel meter monitors the capacitor voltage. The energy storage level can be easily changed in the field. Integral electrical interlock and fail-safe circuitry provide a high degree of operator safety.

Safety Test Panel for Water Cooler
Electrical Safety is the most primary and essential product conformity requirement for any product that uses electricity. The clauses of safety testing of electrical products laid by worldwide agencies such as UL, CE, BIS, etc. are stringent. The products need to pass through tests such as the high voltage test, insulation resistance test, earth bond test, leakage current test and so on. And to conform to such tests, SCR Elektroniks have developed for the testing of washing machines. In addition to the conventional safety tests, test for performance is also included.
