Product Specification

Discharge Test: Periodical discharge test on station batteries is a mandatory requirement for users. These tests ensure reliability, better service and enhance life performance of the battery system. Battery manufacturers specify Yearly / Half Yearly / Quarterly Charge / Discharge cycle tests.

 Advantages: Discharge cycle tests help the users to:
  1. Check initial battery performance against manufactures specifications.
  2. Avoid deterioration of battery system due to early detection defective cells
  3. Guarantee smooth operation of back up system during emergencies.
  4. Improve overall health and life of battery system.
  5. Discharge Resistor: Our unit is designed to perform periodic discharge tests on station batteries. The resistor unit is robust assembly consisting of Copper- Nickel Alloy wire grid elements supported on M.S. tie rods, insulated from each other and the enclosure with Micanite tubes, washers. The unique design of elements allows rapid, natural cooling of resistor bank. Castors are provided for easy mobility.

     Constant Current and Rate of Discharge: The resistor bank has adequate trimming facility (coarse and fine) to maintain a current against falling voltage during discharge operation. D.C contractors / Circuit breakers or knife edge switches are used for switching depending on clients preference. The Rate of Discharge can be accurately controlled and monitored in this system which is can be accurately controlled and monitored in this system which has distinct advantage over other conventional methods of Discharge.


INFORMATION NEEDED FOR DESIGN:  
 
  • Maximum voltage to mimimum voltage of battery required to be discharged.
  • Current steps required for each step of discharge voltage.
  • Material of resistor element.
  • Temperature rise allowed.

 LOAD BANKS:

Load Banks are used for proving power ratings of the Equipments, Generators, UPS Systems etc.

Ratings: AC & DC Load Banks are manufactured as per customer’s requirement in various ratings ranging from 1 KW to 3000 KW.

(Optional) High Temperature Limit Thermostat for resistance elements, Thermal overload for each fan and overflow switches are provided.

Construction: Hot dip galvanized frames fitted with galvanized steel if required otherwise heat resistance aluminium paints are used. All hardware is zinc plated. Stainless Steel hardware is used if required. Frames can be custom made also.
