Control system:

ComAp AMF25 ControllerAuto start and stop control

panel

ComAp AMF25 generator controller integrating digital, intelligent and network techniques is used for automatic control system of diesel generator. It can carry out functions including automatic start/stop, data measure and alarming. The controller uses LCD display, optional Chinese and English display interface with operation easy and reliable.

Parameters: This controller can provide Generator frequency, Under/over speed, Generator volts, Generator current, Engine oil pressure, Engine coolant temperature, Flexible fuel level, Hours run counter, Battery volts, Fail to start/stop, Emergency Stop. Failed to reach loading voltage/frequency, Charge fail, Loss of magnetic pick-up signal, Low DC voltage, CAN diagnostics and CAN fail/error, Mains volts 3 phase, Mains frequency, AMF indications

Protection:♦Low Oil Pressure ♦High water Temperature♦High voltage and low voltage ♦Overspeed♦Volt adjuster and frequency adjuster. ♦Emergency stop ♦Fail to start

Features: ◆ Using microprocessor as a core, symbol LCD with backlight display, the three languages display Chinese, English and Spanish, key touch operation; ◆ Have a RS485 port with Modus communication protocol;

◆ Adapt to 3phase-4wires, single phase-2wires or 2phase-3 wires (120/240V) , 50/60Hz AC power system;◆ Precision measure and display of◆ Measure and display 3 phase voltage, 3 phase current, frequency, power etc. parameter of Mains and Gens;◆ Mains have over voltage, under voltage, loss phase function; Gens have over voltage, under voltage, over frequency, under frequency, over current function;◆ Precision measure and display parameters about Engine◆ Control protection: Automatic crank/stop of diesel engine, load transfer(ATS control) and completely faults display protection;◆ With ETS, idle control, pre-heat control, raises speed control functions, and all types of them are belong to relay output;◆ Parameters setting: Allow user to modify setting and store them by inside internal FLASH memory, the parameters can not be lost even with power off. All of parameters can be set not only from the front panel, but by PC via SG72 (an adaptor, USB-LINK-RS485) module; or, through RS485 port via PC;◆ Most of temperature, pressure, oil level sensor can be directly used, and also user can define sensor curve by themselves;◆ Multiple crank disconnection conditions can be selected.(Speed sensor, oil pressure, gens);◆ Power supply range is wide(8~35)VDC, accommodating to different starting battery voltage environments;◆ All parameters use digital modulation, abandoning analog modulation using conventional electronic potentiometer, more reliability and stability;◆ Modular configuration design, Flame Retardant ABS plastic shell, inserted type connection terminals, flush type installation, compact structure, easy installation.

ENEW50S-3 Technical Data ENG Soundproof Enclosure Specification:E.N Power silent generator is designed by professional acoustic engineers based on 9 years experience, Now we can make the noise of the generator less than 73-78dB(A) at 1m, or 68~73dB(A) at 7m, 63~68dB(A) at 15m.

★ multi-way air intake and exhaust guarantee the power performance of the generator. ★ large-scale impedance combined type silencer effectively reduce noise of the generator. ★ internal high performance rubber damper and flexible materials reduce vibration. ★ Base mounted fuel tank supports the generator running for 8 hours.

★ Transparent viewing window make the control panel clear at a glance.★ Emergency stop button mounted on the canopy exterior for urgency. ★ Cooling fluid injection hole is kept on the ceiling crust. ★ Pipe of lube oil and cooling fluid is mounted on the bottom of generator for easy let.★ Fuel fill and battery can easy be accessed by lockable door. ★ Cooling fan and battery are fully guarded. ★ Heat insulation of exhaust smoke system inside the canopy. ★ Forkman slot is for choice.★ Lifting ear is mounted in the base frame.

★ Cold steel materials of the canopy. ★ Best powder paint. ★ Zinc plated and Corrosion resistance.★ Elegant appearance and reliable quality. ★ Stainless steel locks and hinges.★ Access to all weather conditions.★ Fireproof, waterproof and dustproof. ★ High quality soundproof materials could efficiently reduce noise. ★ Big base fuel tank in the frame guarantee sufficient diesel supply. ★ 180° revolvable and disassemble door for easy maintenance. ★ Concave lockable access door for easy operation and indefectible. ★ Lights inside of the canopy for maintenance.
