The constant current power supply is specifically designed and manufactured for low-voltage electrical users, featuring a constant and unchanging output current, and pure sine wave output. It can be used as an overload current detection test instrument.
This constant current power supply is capable of handling resistive, inductive, and capacitive loads, meeting the requirements of low-voltage electrical appliances for test power supplies.。
Outstanding advantages include high flow precision, available in 1%, 0.8%, 0.5%, and 0.3% levels, catering to different user environments. It ensures a constant output current. Previous large current generator solutions have been problematic due to variations in temperature, copper resistance of wires, connectors, and coils, necessitating frequent adjustments by operators to maintain a steady current, which is time-consuming and energy-intensive. Moreover, the accuracy cannot match this power source. In the production of low-voltage electrical appliances, where current calibration and aging tests are required, using this power source is the optimal choice. This includes settings like the thermal trip current of thermal relays and the measurement of thermal release currents in circuit breakers.
Automated testing for various current levels (projects: voltage, current, frequency, rise/fall time, with recyclable test operations)
Frequency Range: 40-500HZ (optional), Fixed Output: 50HZ, 60HZ (more fixed output frequencies within a broader range can be designed according to customer requirements)
Simulated signal control can be set for users.
Product applications include: AC circuit breakers, AC contactors, mechanical switches, electronic switches, thermal relays, molded case circuit breakers, miniature circuit breakers, and testing equipment for setting rated and trip currents, short-circuit protection current, and instantaneous current switches.
