This constant voltage and constant current programmable control power supply module makes analog integration and digital control functions combined in one.The output voltage is adjustable from0-50.00V, the output current is adjustable from 0-15.00A,Output Power0-1000W.Advanced function, good visual effect, high operability, high precision.

The HT73xx-7 is a low power high voltage series of regulators implemented in CMOS technology which has the advantages of low voltage drop and low quiescent current. They allow input voltages as high as 30V and are available with several fixed output voltages ranging from 2.1V to 5.0V. When the CE input is low, a fast discharge path pulls the output voltage low via an internal pull-down resistor. An internal over-current protection circuit prevents the device from damage even if the output is shorted to ground. An over-temperature protection circuit ensures the device junction temperature will not exceed a temperature of 150°C.

The HT73XX series is a set of three-terminal, low power, high voltage regulators implemented in CMOS technology. The series features extremely low quiescent current which is typically 4mA. They allow input voltages as high as 12V. The device provides large current with a significantly small dropout voltage. The HT73XX consists of a high-precision voltage reference, an error correction circuit, and a current limited output driver. They are available with several fixed output voltages ranging from to 5.0V. CMOS technology ensures low dropout voltage and low current consumption. Although designed primarily as fixed voltage regulators, these devices can be used with external components to generate variable voltages and currents.
