1. Introduction
The MCTS is a multichannel high precision current transducer system, mainly used for the range extension of
power meters. The rack can be equipped with up to six internal power supplies. All internal power supplies are
galvanic isolated from each other and from earth potential. 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) bymeans
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 MCTS 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 MCTS system can be equipped with up to six internal power supplies. 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 either.
Please compare your order papers with our packing list and the received goods.

3. Hardware Installation
The MCTS is delivered with rack mounting brackets for the easy installation into a 19" cabinet. The mounting
brackets can be installed easily with four screws on the left and right side panel. The 19" rack mounting brackets
and the screws are delivered with the system.
3.1. Connection of the current sensor to the MCTS rack
The current transducer will be connected to the MCTS rack with
the delivered D-SUB current transducer connection cable.
3.2. Connection of the current output to an instrument current input terminal
The transducer output current can be directly connected to the
current input terminals of a current or a power meter.
3.3. Connection of the optional voltage output to an instrument voltage input terminal
Before you connect the current output to the voltage input terminal
of a voltage meter 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 MCTS rack and that the output current loop is closed. An unsupplied transducer can be damaged as well
as a sensor with open current output loop. The power and transducer states (ok or error/overload) are visible on
the front panel and available on the status-readout interface (see chapter 6).
Power-LED off: System not powered or channel not installed
Power-LED green: Channel powered
Status-LED off: System not powered or channel not installed
Status-LED green: Transducer connected, normal operation
Status-LED red: Transducer overloaded or interruption in output circuit, switch primary current off!
Example: Four channel MCTS system
Channel 1, 2, 3: Transducer powered, transducer status ok
Channel 4: Transducer powered, transducer overloaded, output loop open or transducer defective
Channel 5, 6: No power supply installed

5. Scaling
Various transducer types are available for the MCTS system. The older types of transducers (IT x0-S) are
specified for a maximum DC- or peak-range. To calculate the AC rms-range of the sensor you have to divide the
DC- or peak range by the square root of 2. The newer transducer types (IT x5-S and IN) are specified for a
maximum rms- and DC-Range. You can find the detailed transducer specification in chapter 7.2.

7.3.2 Total Measuring Resistance at Full Scale
7.3.3. Maximum Burden Resistor depending on Transducer and Connection Cable
The remaining burden resistancecan be calculated by subtraction of the connection cable loop resistance from the transducer totalmeasuring
resistance.
Example IN 1000-S with 15 meters cable 0.34 mm² and 0.75 mm²:
IN 1000-S total measuring resistance: 4 Ω at 1000 Arms
MCTS/TPS/15 loop resistance: 3.14 Ω →Maximum burden resistor = 4 Ω - 3.14 Ω = 0.86 Ω
MCTS/TPS/15/0.75 loop resistance: 1.42 Ω →Maximum burden resistor = 4 Ω - 1.42 Ω = 2.58 Ω

7.4. Burden module specifications
The transducer system delivers the transducer output current at
the 4 mm output terminals on the back panel of the rack. For those
instruments which 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 MCTS rack with a 3-pole D-SUB connector.
7.4.1. Passive plug-on burden resistor specifications
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.

7.4.2. Active plug-on voltage amplifier specifications
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 MCTS 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.

9. Installation of additional internal power supplies (channel extension)
The MCTS system can be ordered with one to six internal power supplies (MCTS2/1CH to MCTS/6CH). The
system can be extended with addition power supplies (MCTS/PS) easily.
For the modification you need one power supply kit MCTS/PS. It consists of
the following components:
- 1 pcs. power supply 50 W
- 1 pcs. primary connection cable
- 1 pcs. secondary connection cable
- 1 pcs. baseplate
- 4 pcs. TORX screw T10
- 4 pcs. toothed washers
Example for systems modification from three to four channels:
Remove the five TORX screws from the top panel and open
the system. Be absolutely sure that the power cord has been
unplugged before you open the rack.
Remove the top panel.

You find the sockets for the connection of the secondary on
the electronics board in the back of the system. The sockets
for the primary AC power connection cables are in the front of
the rack.
Mount the MCTS/PS with the four TORX screws and the four
toothed washers. Primary or secondary connection cables
from adjacent power supplies might be in the way and need to
be removed from the cable harness.
Plug the +/- 15 V secondary connection cable into the socket
P4 of the electronics board.
Plug the primary connection cable into the connection block.

Fix the primary and secondary connection cable with some
cable ties at the cable harness and close rack.
Connect to power plug, switch the system on and check the
channel power.
Perform a safety test according VDE 0701 / 0702 (EN 62638).
