SLICE Dual Current Controller
- Currents up to 2,000 mA per channel
- Low noise
- High-modulation bandwidth
- Ideal for pump diodes and optical amplifiers
Made in the USA The SLICE-DCC is a compact, efficient CW current controller for driving pump diodes; semiconductor optical and tapered amplifiers; and diode, interband, and quantum cascade lasers. Part of the Vescent SLICE series of high-performance, economical photonic control electronics, SLICE-DCC offers two channels of low-noise current control. Proprietary self-adjusting power supply technology automatically sets the compliance voltage to as high as 12 V but no higher than necessary to drive your load‚ allowing you to drive a traditional diode or a quantum cascade laser with the same device and the same efficiency.
The two channels operate independently‚ including the automatic compliance voltage. Controlled via a touchscreen or an API command set, the SLICE-DCC includes all the features you expect from your current controller: high modulation bandwidth, power leveling, interlocking, and current limiting & diode protection circuits.
The SLICE-DCC employs Vescent's proprietary hybrid switching / linear power supply technology to deliver unsurpassed current noise performance.
