MHCO
General Characteristics
D.C. MEASURING CONVERTER
• Converter for D.C. Current and/or Voltage measurement.
• Direct connection to D.C. mains rating up to 4 kVcc.
• Fully isolated multi-voltage power suppy.
• Fiber optic connection between HV transducer and LV
reciving unit.
• Measurement channel fully diagnosed
The technical specifications reported are not binding and they
should be agreed in the related contract.
Transducers
The transducer MHCO provide a measurement of current or voltage fully isolated and safe.
The transducer includes three components: Transmitter, Riceiver, Fiber Optic.
Transmitter
The Transmitter, connected to the system, acquires the inputs and througth a fiber optic transmits it to the receiver.
The test voltage isolation between inputs and power supply is equal to 20kV 50Hz 1min.
Voltage Transmitter
MHCO-TV Converter for Voltage measurement direct connection to D.C. line up to 4000V
(voltage divider inside)
Current Transmitter
MHCO-TI Transmitter for measuring current, directly connected to the high voltage line through normal shunt .
Current/Voltage Transmitter
MHCO-TVI Transmitter current and voltage in a single unit directly connected to the high voltage line
(max 4000Vcc) through the shunt.
Riceiver
Current and Voltage Receiver
MHCO-RV
MHCO-RI

current measurements
Fiber Optic
The optical fiber used for the connection between the transmitter and receiver (equipped with ST connectors) must have the following
characteristics: Plastic: 200u HCS - Glass: 62.5/125
The standard length of the optical fiber is 5 meters. (other lengths available on request).
The Receiver connected via optical fiber to the transmitter has three configurable linear analog outputs, - one relay output for alarm and
internal fault.
