The YS118C programmable multifunctional standard power source is an intelligent power calibrator with advantages such as high stability and easy operation,

It is an ideal upgraded product for verifying "AC/DC voltmeters, AC/DC ammeters, frequency meters, phase meters, AC/DC power meters, and power transmitters".

Its characteristics are phase angle closed-loop, voltage closed-loop, and current closed-loop, thereby ensuring low drift and annual stability.

In addition, the instrument is equipped with a full duplex RS232 interface and a GPIB interface that complies with the IEEE488.2 standard, which can be easily connected to a PC and is suitable for automatic testing systems.
