GSM-20H10 provides four-quadrant
operation of ±210V/±1.05A/22W. The first
and third quadrants operate as power
supplies to supply power to the load. The
second and fourth quadrants function as
loads to consume power internally. Voltage
value, current value and resistance value
can be measured while operating the
power supply or load function with an
accuracy of 0.012% and a resolution of
For interfaces, this product supports standard SCPI commands and provides RS-232, USBTMC,
LAN, GPIB (optional) interfaces to meet users’ different interface needs.
