SENECA current transformers with analyzer functionality-0

T203PM is a single-phase AC / DC TRMS network analyzer with ModBUS interface, analog and digital output, inputs with 3 current measuring ranges depending on the version (100/300/600 A) and voltage 290 Vac, 1000 Vdc.

The instrument performs direct current and energy measurements without the use of external current transformers. T203PM is measured by:

  • voltage AC / DC,
  • current,
  • active and reactive power,
  • power factor,
  • frequency,
  • harmonic distortion (THD).

Values are transmitted via analog or digital output.

The T203PM can analyze up to the 21st harmonic and is equipped with a digital contact that can be used as an alarm or counter.

Configuration is performed using EASY SETUP 2 software and Micro USB programming port.

T203PM analyzers are especially durable because they have a wide operating temperature range -25 ... + 65 ° C, insulation up to 3 kVac (on empty conductors), safety class CAT. III 600V and 1kV (isolated driver).

The devices can be mounted on an IEC EN60715 35 mm DIN rail using the appropriate mounting.

In combination with gateway devices such as Z-KEY or R-KEY-LT, it can be easily integrated into an Ethernet network and a central monitoring system.
