Instek PEL-507-500-30 – Programmable DC Load (500V/30A/700W)

• Programmable DC electronic load
• Maximum power: 700W
• Maximum current: 30A
• Maximum voltage: 500V

The PEL-500 series single-channel electronic load has a total of 5 models and provides 0~80V/ 0~500V voltage operating ranges and 250~700W power operating range. The series can be applied to R&D, quality control, ATE system and production test, including voltage source/current source test; switching power supply transient response; constant voltage mode for current limiting test; battery simulation; and battery discharge test.

The chart below outlines main performance characteristics of each.

The Surge function allows users to set Surge current, Normal current, Surge Time and Surge STEP according to test requirements.

Surge Time can be set from 10 to 1000ms, and Surge STEP can be set from 1 to 5.

Surge and normal current ranges for surge testing are model dependent:

• PEL-503-80-50
• 0-50A
• PEL-504-80-70
• 0-70A
• PEL-504-500-15
• 0-15A
• PEL-507-80-140
• 0-140A
• PEL-507-500-30
• 0-30A

The battery discharge test function can determine the conditions to stop the discharge according to the test requirements of the DUT, including setting the stop discharge voltage (Vbatt), discharge capacity (AH, WH) and stop discharge time.

The GO/NG function is applied to monitor the test result. When the test result exceeds the preset upper/lower limit, the front panel display screen will display NG. Otherwise, GO is displayed. The GO/NG function can edit the working procedures of the test in CC mode/CR mode/CV mode/CP mode. After the test procedures are executed, the test result will be displayed on the front panel display screen, which is represented by GO or NG.

With the operating mode of constant current, the PEL-500 series electronic load will sink a current in accordance with the programmed value regardless of the input voltage.

In Constant Resistance mode, the PEL-500 series electronic load will sink a current linearly proportional to the load input voltage in accordance with the programmed resistance setting.

In Constant Voltage mode, the PEL-500 series electronic load will attempt to sink enough current until the load input voltage reaches the programmed value.

In Constant Power mode, the PEL-500 series electronic load will attempt to sink load power (load voltage * load current) in accordance with the programmed power.

The charts below outline the operating areas for the PEL-500 product series. Each load module is capable of sinking a wide range of voltage and current values. The load modules are limited by the maximum power they can sink.
