Apex is a brand of Electrozirve

HZ601 Collection Programmable DC Standard Power Source is a high-level meter & power source integrated instrument which invested by Shenzhen Hangzhi, who gathering high-tech talents, adopting the unique electronic compensation linear sampling technology which ensure full range linearity of small signals (�µA & mV level) and super signals (50A & 1000V). Voltage and current could be output simultaneously and output DC power as well. Besides output, the input voltage (or current) can be measured simultaneously. It builds-in DC meter verification program to easy users.

High output stability: DC voltage, current output stability can reach 0.005% / min.
Wide output range: standard source output DC voltage range 0 mV-1100V
Standard source output DC current range: 0�µA-55A
Wide measurement range: measurement input DC voltage range 0mV-1100V
Measurement of the input DC current range: 0mA-55A
Support self-calibration: software self-calibration to the output input gear and does not need to open the case
Soft start: built-in soft start, preset load circuit,output from zero quickly rise to the set value, no impact on the load
