1. Introduction
The TPS is a power supply unit for the high precision CT current transducers, mainly used for the range extension of current-
and power-meters. 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 unpowered 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 are visible on the front panel. The information of the status-
readout-interface on the back panel can be used to switch off the primary current via a relay or a PLC in case the transducer is
overloaded, the TPS is switched 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.
2. Receiving of goods
The TPS system usually is delivered together with a high precision CT transducer and a connection cable. The CT transducers
are available from 100 A up to 2000 A. Connection cables are available in different lengths. Passive plug-on shunts and active
plug-on voltage amplifiers can be ordered as an option. A status-readout cable and different current and voltage output cables
are available as options either.
Please compare your order papers with our packing list and the received goods.

3. Hardware Installation
The TPS is delivered as a desktop unit. 19” rack mounting brackets are available as an option. The brackets can be installed
easily with four screws on the left and right panel side.
3.1. Connection of the TPS current output terminals to the current input terminals of a current- or power-meter
The current transducer will be connected to the
TPS rack with the delivered D-SUB current
transducer connection cable.
The transducer output current can be connected
directly to the current input terminals of a
current or a power meter with 4 mm safety
leads.
3.2. Connection of the optional plug-on voltage output module to the voltage input terminals of a multimeter
The current transducer will be connected to the
TPS rack with the delivered D-SUB current
transducer connection cable.
Before you connect the current output to the
voltage input terminals of a multimeter or the
sensor input terminal of a power meter you have
to transfer the output current into a voltage
signal. For this purpose, passive plug-on burden
resistors and active plug-on output voltage
amplifiers are available.

4. Operating instructions
Before you switch on the primary current through the current transducer, be sure that the transducer is powered by the TPS
rack and the output current loop is closed. An unpowered transducer can be damaged as well as a sensor with open current
output loop. The power and transducer status (ok or error/overload) are visible on the front panel and available on the status-
readout interface (see chapter 6).
Power-LED off: TPS system switched off
Power-LED green: TPS switched on
Status-LED off: TPS system switched off
Status-LED green: Transducer connected, normal operation
Status-LED red: Transducer overloaded or interruption in the output loop, switch primary current off!

5. Scaling
Six transducer types are available for the TPS system. 100 A, 200 A, 400 A, 500 A, 1000 A and 2000 A. To adapt the sensor to
the power meter you need to program either the transducer ratio or the scaling factor in the instrument software.

Maximum Burden Resistor depending on Transducer and Connection Cable
The remaining burden resistance can be calculated by the subtraction of the connection cable loop resistance from the transducer total measuring resistance.
Example CT 1000 with 15 meters cable 0.34 mm² and 0.75 mm²:
CT 1000 total measuring resistance: 4 Ω at 1000 Arms
MCTS/TPS/15 loop resistance: 3.14 Ω →Maximum allowed burden resistor = 4 Ω - 3.14 Ω = 0.86 Ω
MCTS/TPS/15/0.75 loop resistance: 1.42 Ω →Maximum allowed burden resistor = 4 Ω - 1.42 Ω = 2.58 Ω

7.4. Burden modules
The TPS system delivers the transducer output current at the 4 mm output
terminals on the back panel of the rack. For those instruments that don’t have
current input terminals, optional high precision passive and active plug-on
burden modules with very low phase angle error are available. The active
voltage output modules are supplied by the TPS unit with a 3-pole D-SUB
connector.
7.4.1. Passive plug-on burden resistors
Passive plug-on burden resistors are available from 1 Ω to 50 Ω. The burden resistor is limited by
the transducer and the length of the connection cable. For higher output voltages active plug-on
burden amplifiers are available.

The output voltage level the transducer can drive is limited. The active plug-on
burden modules combine a very precise burden resistor with a highly accurate
voltage amplifier. The plug-on burden voltage modules deliver 7 Vrms (± 9.9 Vpk)
at transducer nominal value. The active plug-on voltage output modules are
powered by the 3-pole D-SUB on the back panel of the system.

8. Switching off and deinstallation
Before you switch off the TPS rack, open the output current loop or remove any cable between rack and sensor, make sure
that the primary current is switched off. An unpowered transducer can be damaged.
