The above test is capable to test samples having low resistance and where high direct current injection is required like switches, busbars, relays etc. Input: 3 phase, 415 volts, 50Hz AC, subject to variation between 380 to 440 volts. Output: By smooth variation of three phase Auto-Transformer, which supplies variable voltage to the primary of a three phase double wound, delta/double star rectifier transformer, secondary of which is connected to a rectifier stack using silicon diodes along with surge suppressor. The D.C. output is obtained from the rectifier bank output and the star points of the transformer through an interphase transformer. Series: LVHDCXXU; XX denotes DR or OC i.e. either the transformer will be dry type or oil cooled type.
U denotes no. of units ? either one (1) or two (2). Type: YYYAZZV; YYY denotes the maximum current capacity in Amp.
While, for YKAZZV; Y denotes the maximum current capacity in kAmp.
ZZ denotes the open circuit voltage rating. - We manufacture these sets in wide range upto 6KA and of various capacities.
- Duty Cycle: Intermittent.
- Protection against overload & short circuit is provided. ?Zero Start Interlock? protection is also incorporated.
- Metering: Analog Voltmeter & shunt operated Ammeter. Digital meters can be provided at extra cost.
NOTE: Beside above standard models we will be glad to manufacture High D.C. Injector of other current &
voltage rating as required by the customer.
This set can also be used as loading unit for electroplating applications. |
