2. Functions and Features

2.1 Energy measurement by phase; total energy is the summation of three phase energy pulses with less mutual interference

2.2 Reactive energy measurement via complementary passive phase circuit with high accuracy and reliability

2.3 New design adopted with less influence from frequency, voltage and harmonics on measurement accuracy; no calibration is needed during long working period

2.4 Three phase power supply with phase break indication. Measurement accuracy wont be affected if one or two phases are broken

2.5 Wide operating voltage range

2.6 Remote test impulse output

2.7 RS485 port: DSS(X)51B, DTS(X)51B

RS485 and infrared port: DTS(X)51C
