1 AND 2 PHASE POWER TRANSMITTER ITL-100
  
One and Two Phase Power Transmitter

ITL-100 Power Transmitter computes average electrical power P= I x U x cosphi consumed by a load, and converts power to a proportional 0-20mA output current. The wide frequency range, DC to 10kHz yields excellent accuracy for sinusoidal as well as nonsinusoidal signals (thyristor controlled circuits).
ITL-100 Series

Features

  • Measures power U x I x cosphi

  • 0.2% accuracy

  • DC to 10kHz (100kHz)

  • Output 0-20mA

  • Suitable for 1- and 3-phase
    systems, and pulsed circuits

  • Output isolated from circuit

  • Simple hook-up

 

Introduction

Increased frequency range (Option 01: DC to 100kHz) enables the transmitter to measure power of pulsed systems. The 0-20mA output signal is galvanically isolated from input and electronics supply. 
Two or three transmitters can be hooked-up to monitor total power of a 3-phase system by simply adding the transmitter output currents in a ammeter or a common resistor.
The transmitter is well suited to monitor and control the power consumption of electrical equipment.

ITL-100 Specification (20°)
ITU-100 Current Transmitter Current Ranges 2A, 5A, 10A and 20A
Voltage Ranges 120V and 250V. Input impedance 4.7MΩ
Power Ranges 240W, 600W, 1200W, 2400W for 120V range
500W, 1250W, 2500W, 5000W for 250V range
The transmitter is fitted with 1 voltage range and
1 current range. The power range (corresponding
to 20mA) results by multiplying voltage range times
current range.
Accuracy 50-60Hz, ±0.3% (typ.0.2%) of output
DC-1kHz, ±0.5% of output
1-10kHz, ±2% of output
10-100kHz, ±3% of output (Option 01)
At cosphi=0.5 multiply accuracy percentage
by 2.
Output 0-20mA for nominal power range
max. linear output 0-30mA.
Linearity ±0.1% of output, 2-25mA
Temp. coefficient 0.02% of full scale (20mA)
Response time 1 sec. for 0-90% of final value
Crest factor Voltage peaks and current peaks 5 times
selected range will not degrade accuracy
Input/Output isolation 2kV, 50Hz, 1 minute
input/output capacitance = 20pF
Output load Rb 0-300Ω max. at 30mA, output current
change = -5uA/100Ω
Common mode rejection 100dB, 50Hz, Rb=100Ω
Ambient temperature -10° - 50°
Supply 230V (+20%/-10%) / 20mA (110V on request)
