DDDL-4000JZ AC DC generator (referred to as the up flow reactor), developed by our company developed test equipment, which combines the advantages of similar products at home and abroad in a body, and adopts the technology of numerical control, anti-interference ability strong, and a generation of up flow is compared, due to the low power consumption and large capacity self coupling voltage converter and high permeability core, with the advantages of high output power, small volume, light weight, etc.. Mainly used for thermal relay, motor protector, contactor, breaker, air switch, switch cabinet, circuit breaker, protection screen check.
The built-in digital ammeter for direct reading
The high accuracy level 0.2
The big power, small volume, strong load ability
The test precision is high
