LOADING RHEOSTATS (RESISTIVE LOAD)

APPLICATIONS: 
Loading Rheostat is a device specially designed to meet the requirements of Engineering Laboratories, Electrical Test Rooms and Industries. It is used for loading transformers, power generators, supply mains etc. neatly and efficiently. It can also be used advantageously for regulating current and adjusting voltage besides its application for calibrating meters and thus eliminating the need for graded rheostats.

CONSTRUCTION:
Loading Rheostats equipment consists of normal wire wound resistors made of constantant wire (nickel - copper alloy) having very low temperature co-efficient. The whole system is enclosed in a sturdy grilled metal box providing free cross ventilation on all sides for efficient cooling. On the front side controlling switches and regulators meant for various purposes are provided on a bakelite panel. The box is fitted with four castor wheels suitable for easy movement from place to place in a laboratory. Switches sequence will be minimum 6 and maximum 10 as per your requirements. SINGLE PHASE LOADING RHEOSTATS: SUITABLE FOR OPERATION ON 230V A.C. 50 Hz.
CAPACITY : 0 - 3 kW, 0 - 5 kW, 0 - 7.5 kW , 0 - 10 kW, 0 - 15 kW.
--DO-- 3 Phase Loading Rheostats suitable for operation on 415/440V. A.C. 50 Hz.
CAPACITY : 0 - 5 kW, 0 - 7.5 kW , 0 - 10 kW, 0 - 15 kW.
