PERFORMANCE AND CHARACTERISTICS
Main characteristics are as bellow:
—
With ARM-based 32-bit SCM, high integration of hardware and more reliable;
—
240x128 LCD with backlight, multilingual interface (including English, Chinese or other languages)
which can be chosen on site, making commissioning convenient for factory personnel;
—
Improved LCD wear-resistance and scratch resistance due to hard screen acrylic;
—
Silicon panel and pushbuttons for better operation in high/low temperature environment;
—
Two RS485 communication ports enable remote control, remote measuring, remote
communication via MODBUS protocol;
—
Fitted with CANBUS port and can communicate with ECU equipped with J1939. Not only can you
monitor frequently-used data (such as water temperature, oil pressure, engine speed, fuel consumption
and so on) of ECU machine, but also control start, stop, raising speed and speed droop via CANBUS
port;
—
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 of Mains/Gen, Mains/Gen frequency, Gen 3-phase current, Gen
power and Gen voltage harmonic parameters;
—
For Mains, controller has over voltage, under voltage, over frequency, under frequency, loss of
phase and phase sequence wrong detection functions; For generator, controller has over voltage,
under voltage, over frequency, under frequency, high unbalanced voltage, high total harmonic
distortion, over current, earth fault, high unbalanced current, low power factor, over power, reverse
power, loss of excitation, loss of phase, phase sequence wrong detection functions;
—
Synchronization parameters: voltage difference between mains and gen, frequency difference
between mains and gen, phase angle difference between mains and gen;
—
Multiple running modes in auto state: with load running, off load running, island running, parallel
running on demand;
—
Soft load transfer function in paralleling/splitting;
—
3 fixed analogue sensor inputs (temperature, oil pressure and fuel level);
—
2 configurable analogue sensor inputs can be set as sensors of temperature, oil pressure or level;
—
Oil pressure sensor and configurable sensor input 1 can directly connect with
resistive/current/voltage sensors, while other sensor inputs can directly connect with resistive sensors,
and for connecting voltage/current sensors, please make it clear before the order;
—
More kinds of curves of temperature, oil pressure, level sensors can be used directly and users can
define the sensor curves by themselves;
—
Precisely collect various engine parameters, including temperature, engine oil pressure, fuel level,
speed, battery voltage, charger voltage, total running time and total start times etc.;
