Atec Chroma-63800 Series - Manual

Programmable
AC/DC Electronic load
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 giving reliable and unbiased
test results.
The 63800's state of the art designed uses
DSP technology to simulate non-linear rectified
loads in a 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 system stability.
Comprehensive measurements allow users
to monitor the output performance of UUT.
Additionally, voltage & current signals can
be routed to an oscilloscope through analog
outputs. The instrument's GPIB/RS232
interface options provide remote control &
monitor for system integration. In addition,
built-in digital outputs may be used to control
external relays for short circuit (crowbar)
testing.
Chroma's 63800 Loads also feature fan speed
control ensuring low acoustic noise. The
diagnosis/protection functions include self-
diagnosis routines and protection against over-
power, over-current, over-voltage and over-
temperature.
