Amp-Line, Constant current sources and amplifiers provide steady output current independent of the load and input power line with variations. Usage of these constant sources and amplifiers include generating magnetic fields, testing and qualifying products such as circuit breakers, relays, transformers, meters, etc. The "CR-A" series constant current mode power amplifiers are stable and easy-to-use power amplifiers designed with linear circuitry.

Their standard output ranges include 0 - 1 A, 0 - 2 A, 0 - 5 A, 0 - 10 A, 0 - 20 A, 0 - 25 A, 0 - 40 A, 0 - 50 A, 0 - 100 A. Custom output ranges (up to 1000 A) can be specified by customers. Constant current mode power amplifiers are also called transconductance power amplifiers. The frequency response of our transconductance amplifiers is from 47 Hz to 2K Hz. If a variable-frequency constant current source is needed, the combination of a function generator and one of our transconductance power amplifiers will be an ideal solution.

Please consult with the factory if higher output frequencies are needed. Our constant current power amplifiers and power sources can power up highly inductive loads with low distortion. We manufacture multi-channel constant current power amplifiers and constant current sources.


Market Applications:

Testing: Our products are utilized in applications such as testing of Helmholtz coils, piezo elements, circuit breakers, protective relays, lamps, watt-meters, transformers, inductors, capacitors, ferrite cores, etc. Our products are especially good for highly inductive loads and capacitive loads which require PD free powering.
