MILLI VOLT DROP TEST SET

Product Code : TSM003

Description: This is a portable DC Injection Set suitable to observe millivolt drop across low resistance elements, contacts, switches, D.C. motor commutator segments etc. Input : 230 volts, 50Hz, 1Phase, AC upto 300A. 400/415 V, three phase, 4 wire, 50Hz. , AC above 300A. Output : Continuously variable from zero to maximum rated current required. Series: MVDTXPYYU; X denotes single phase input (1) or three phase input (3); YY denotes DR or OC i.e. either the transformer will be air-cooled or oil cooled type. U denotes no. of units – either one (1) or two (2). Type: Y1Y1Y1AZZV; Y1Y1Y1 denotes the maximum current capacity in Amp. While, for Y1KAZZV; Y1 denotes the maximum current capacity in kAmp. ZZ denotes the open circuit voltage rating. We manufacture these sets in wide range up to 3KA and of various capacities. Duty Cycle : 5 minutes ON & 10 mins. OFF. Sets of other duty cycle can also be manufactured at extra cost. Units : 1 unit upto 500A. 2 units above 500A upto 3000A. Transformer : Air-cooled upto 1000A. Oil cooled above 1000A upto 3000A. Step down rectifier transformer with full wave rectifier bank consists of 4 nos. silicon diodes along with surge suppressor. Protection against overload & short circuit is provided. “Zero Start Interlock” protection is also incorporated. Metering: Analog millivoltmeter, voltmeter & shunt operated ammeter. Digital meters can be provided at extra cost. One set of probes to measure millivolt drop between two points of test sample is provided.
