![]() ![]() A bit of perfboard provides a home for the bulk of the circuit. The power output range is 10 to 1000 watts. It also protects VCC from undesired shorts and transients coming from the source. Generating 0A to 5A with a compliance range of 4V to 28V, it offers two advantages: The 12-bit D/A converter makes it digitally programmable, and the switch-mode step-down regulator (IC1) makes it more efficient than the Description: The Model 121 programmable DC current source is a precision instrument suitable for bench-top use or panel-mounted operation in labs, test facilities, and manufacturing environments. Accurate and stable current supplies are generally needed in electronic labs especially for creating V-I curves, charging and discharging batteries, preloading power supplies and for many other purposes and applications. The maximum programmable output current value is set using software and an adjustment resistor. Programmable current source ic Our Smart Current LED drivers also feature a 12Vdc/ 200mA max auxiliary power output. ![]()
