Introduction
The TPS is a single channel power supply for the LEM IT- and IN-current transducers, mainly used for the range
extension of power meters and other instruments. The current output terminals deliver the transducer output
current on the back panel. Passive plug-on burden resistors and active plug-on voltage amplifiers are available
as an option. The status-readout-interface delivers the transducer status (ok or overload/error) by means of
internal galvanic isolated relay contacts.
Warning
Please be aware that an unsupplied transducer or a transducer used with open output can be destroyed. The
same can happen if a transducer is heavily overloaded. Power and transducer status is visible on the front panel.
The status-readout-interface on the back panel can be used to switch off the primary current in case the transducer
is overloaded, the TPS power is off or the output loop is interrupted. All these events will change the transducer
status to error on the front panel led and the status-readout-interface. There is more information about the status-
readout-interface available in chapter 6.

Receiving of goods
The TPS system is able to power one transducer of the LEM IT- and IN-series. A multi channel transducer system
MCTS is available either. There are various transducer types available from 60 A up to 2000 A. Connection cables
are available in different lengths. Passive plug-on shunts and active plug-on voltage modules are available as an
option. A status-readout cable and different current and voltage output cables are available as options too.
Please compare your order papers with our packing list and the received goods.
