PERFORMANCE AND CHARACTERISTICS
♦
HGM8100A series controller has two types:
HGM8110A
: ASM (Automatic Start Module), used for single automation systems;
HGM8120A
: AMF (Auto Mains Failure), updates based on HGM8110A, moreover, has mains
electric quantity monitoring and mains/generator automatic transfer control function, especially
for automatic system composed by generator and mains;
♦
With ARM-based 32-bit SCM, highly integrated hardware, new reliability level;
♦
Vacuum fluorescent display (VFD), selectable Chinese/English interface which can be chosen at
the site, making commissioning convenience for factory personnel;
♦
Widely temperature range: (-40~+70)°C, can be used in extreme temperature environment;
♦
Suitable for 3-phase 4-wire, 3-phase 3-wire, single phase 2-wire, and 2-phase 3-wire systems with
voltage 120/240V and frequency 50/60Hz;
♦
Collects and shows 3-phase voltage, current, power parameter and frequency of generator or
mains;
Mains
Line voltage (Uab, Ubc, and Uca) V (unit)
Phase voltage (Ua, Ub, and Uc) V (unit)
Frequency f Hz (unit)
Generator
Line voltage (Uab, Ubc, and Uca) V (unit)
Phase voltage (Ua, Ub, and Uc) V (unit)
Frequency f Hz (unit)
Load
3-phase Current Ia, Ib, Ic A (unit)
Active power (P) kW (unit)
Apparent power (S) kVA (unit)
Power factor (λ)
Accumulate total generator power (W) kWh (unit)
♦
For Mains, controller has over and under voltage, over and under frequency, loss of phase and
reverse phase sequence detection functions; For generator, controller has over and under voltage,
over and under frequency, over current, over and reverse power, loss of phase, reverse phase
sequence detection functions;
♦
3 fixed analog sensors (temperature, oil pressure and liquid level);
