P30H DC Signal Transducer

With Data Logging

  • DC current/voltage input
  • 0>10V, 4>20mA and 1 relay output
  • RS485 Master or slave
  • Wide voltage, AC/DC control

Product description

The P30H measuring transducer has been developed for d.c network applications found in such industries as photovoltaic, railway and telecoms,

 

P30H measures and records d.c current, voltage, power energy and other d.c parameters.

The unit is available in 3 versions

  • basic
  • with SD/SDHC card
  • Ethernet with built in www.server

 

This unit can be easily interfaced into existing systems to provide a complete solution to your d.c measurement requirements.

The clear LCD display shows the measured values and the status of the alarm outputs. The unit can be programmed from the front panel buttons or via a PC using the free e-Con software.

Inputs & measuring ranges

Measured and calculated values by the transducer

● d.c. voltage U (direct or through additional resistor D5)

● d.c. current I (direct through shunt)

● power of d.c. current P

● voltage dierence in time dU (5 s, 30 s, 1 min, 5 min or 15 min)

● current dierence in time dI (5 s, 30 s, 1 min, 5 min or 15 min)

● voltage averaged over time UAV (15, 30 or 60 min.)

● current averaged over time IAV (15, 30 or 60 min.)

* – version in set with additional resistor D5 (Ku≠1),

KU – voltage ratio (Primar.U/Second.U),

KI – current ratio (Shunt I/Shunt mV, KI = 1000 e.g. for shunt 150 A/150 mV)

The maximum range display of measured values on the LCD display are -99999G…99999G.
These ranges depend upon the size parameters of the primary and secondary voltage divider and the shunt ratio (parameters Primar.U, Second.U, Shunt I, Shunt mV).
