ARRAY 3721A Programmable Electronic Load 400W 5.00 2

Introduction：
3720A and 3721A Electronic Loads provide an adaptable, and functional asset wherever power sources need to be tested.These units are designed to provide high reliability, great performance, and ease of operation with multiple functionality.

High Reliability

Protective circuitry provides over-current, over-voltage, over-power, over-temperature and reverse polarity protection to ensure the protection of the electronic load; A high-speed, power limiting circuit can limit input power rapidly when it is overloaded, thus there is no need to interrupt testing. Equipment adaptability to complicated operational environments is thereby greatly enhanced.

Great Performance

Circuit improvement greatly enhances the dynamic response of CR mode and widens the application scope of that mode;

Multifunction

• Equipped with four basic test functions: CC, CV,CR, CP;
• High-speed transient operation with separate high/low lever time and rising/falling time control;

     

Easy Operation

• Design optimized for portability and rugged reliability;
• Logical keypad design and convenient test operation;
• Easy-to-set test parameters coupled with a powerful sequence editing function;
• All electronic calibration - therefore no need to dismantle the equipment-chassis;
• Firmware can be updated online.

Specifications

(The warm-up time is 30 minutes. Specifications indicate warranted performance in the 25°C ± 5°C region of the total temperature range).
