ARRAY 375X | Series Electronic Load
ARRAY 375X Series electronic load is a new-generation high-performance programmable electronic load researched by ARRAY ELECTRONIC CO., LTD, which provides powerful test function and friendly human-machine interface.
The electronic load is equipped with RS232, USB and GPIB interface and supports SCPI standard commands for programmable instrumentation and LabView development platform, which is widely used in the scientific research and production field of aerospace, shipbuilding, auto electronics, solar cell and fuel cell.
Four basic testing modes: CC, CV, CR and CP; twelve basic working modes: CCL, CCH, CVL, CVH, CRL, CRH,
CP, CCL+CV, CCH+CV,CRL+CV, CRH+CV, CP+CV;
The 16 bit D/A converters and 24 bit A/D converters incorporated, provide the equipment with greatly
enhanced setting and measurement resolution. The D/A conversion rate can reach 500 KHz and the high
-speed performance is overall increased;
Minimum operating voltage is less than 1.8V at the load’s full rated current. The maximum current can
be achieved even though the input voltage is 0V, which is especially suitable for the fuel cell, solar
cell, auto charger and other new energy test application. The load is with powerful protection function
and is reliable in the most complicated test environment;
High resolution TFT-LCD display;
High-speed transient test function: the maximum test frequency can reach 50 kHz and the current response
speed can be 15A/us..
Powerful sequential test function: the minimum step time is 10us and the maximum step time is 99999s.
Cyclic times can be set freely and can be chained to another sequence to realize more complex test
procedure;
The high-efficiency intelligent cooling system can ensure the equipment has a long-term, full-power,
trouble-free and continuous work;
Automatic ON/OFF function effectively simply the test operation;
The combined use of knob and number keypad makes the operation more convenient;
Save/Recall function can save multiple groups of common settings;
With OCP, OPP, OTP protection function and OV, RV alarm function;
Supporting SCPI and LabView and providing necessary PC software.
Specifications:
(The warm-up time is 30 minutes. Specifications indicate warranted performance in the 25°C ± 5°C region of the total temperature range).
