High Power DC Electronic Load 63200 Series Quick Start Guide
WARNING
Recommended safety precautions:
Ensure wiring, external circuit elements, etc are sized to the maximum
rating of the LOAD even if intended UUTs are smaller. This provides
protection in the event that users inadvertently apply full rated voltage,
current or power or larger UUTs are tested in the future.
User should take into account the power dissipated in the output cable
under worse case conditions to ensure the wire the gauge and cooling is
adequate.
Ensure the load always receives adequate ambient cooling air at all times
and air filters, ducks, etc are maintained regularly. If loads are used with
a cabinet, precautions should be taken to minimize heating within the
cabinet.
If the UUT may be damaged or an unsafe condition may occur in the
event of a load short circuit (e.g. certain types of batteries), or if there is
no means of de-energizing the UUT in the event of a load failure, user
may consider including a suitably rated circuit breaker, fuse or other
means of disconnecting the load from the UUT under emergency
conditions.

Remote Sensing Connections

There are two sensing points for the Electronic Load.
measurement at Load terminal, and another is measurement at Vsense.
The Load will automatically switch to Vsense when Vsense terminals are
connected to UUT, otherwise it will measure at Load terminals. Remote
In case the MOSFETs in the electronic load fail in the short
circuit status, there is no internal means of interrupting the
current that is flowing from the Unit Under Test (UUT).
User should consider added external circuit elements for
protection as described below. MOSFET failures are rare
when instruments are used within their rated
voltage/current/power and temperature ranges.
If there are any questions regarding safe operation of the
equipment or adding external protection circuits, please
contact Chroma's service personnel.
