4-Channel Coil Driver
Request a price quote.
ColdQuanta’s four-channel coil driver consists of four bidirectional voltage-controlled current sources that are designed to drive inductive loads. The output currents are directly proportional to the input voltage, i.e. an input voltage of +1.0 V will set the output current to +1.0 A. Each channel is independently capable of driving up to ±3 A. All four channels are floating, and each has its own set of controls, indicators, inputs, and outputs. Balanced, differential inputs isolate the coil driver from control electronics. The system is designed to work with ColdQuanta’s 3 axis coil assembly in a MOT + bias field configuration.
