Chroma's 63800 Series AC&DC Electronic Loads are designed for testing Uninterruptible Power Supplies(UPS), Off-Grid Inverters, AC sources and other power devices such as switches, circuit
breakers, fuses and connectors.

The Chroma 63800 Loads can simulate load conditions under high crest factor and varying power factors with real time compensation even when the voltage waveform is distorted. This
special feature provides real world simulation capability and prevents over-stressing thereby gives reliable and unbiased test results.

The 63800's state of the art design uses DSP technology to simulate non-linear rectified loads with its unique RLC operation mode. This mode improves stability by detecting the impedance
of the UUT and dynamically adjusting the load's control bandwidth to ensure the system's stability.

Comprehensive measurements allow users to monitor the output performance of the UUT.Additionally, voltage & current signals can be routed to an oscilloscope through analog outputs. The GPIB/RS232 interface options provide remote control & monitor for system integration. The builtin digital outputs may also be used to control the external relays for short circuit (crowbar) testing.

Chroma's 63800 Loads feature in fan speed control to ensure low acoustic noise. The diagnosis/ protection functions include self-diagnosis routines and protection against over-power, overcurrent,
over-temperature and over-voltage alarm.
