Electronic Engine Control
1 OVERVIEW
HMP300 power integrated protection module integrates digital, intelligent and network technology,
and is used for collecting generator-set data (voltage, current, power and frequency) and related action
output for data errors to protect the device. It fits with display, optional Chinese and English
bilingual interface, and it is reliable and easy to use.
HMP300 power integrated protection module adopts micro-processor technology with precise
parameter measuring, fixed value adjustment, set value adjusting functions etc. All parameters can be
configured from front panel or through LINK interface via PC. It can be widely used in all types of
marine/land electrical device with compact structure, advanced circuits, simple connections and high
reliability.
2 PERFORMANCE AND CHARACTERISTICS
Main features are as below:
132x64 display with backlight, selectable language interface (Chinese and English), push-button
operation.
Equipped with LINK communication port; Through LINK interface on PC, data and parameters can be
monitored and adjusted.
Equipped with CANBUS port, which can connect with HMC9000/HMC6000 module to realize power
and engine data collecting and display at the same time.
Differential protection function, and controller will issue related alarm information after differential
protection is active.
Protections for over/under voltage, over/under frequency, reverse power, over power and over
current.
Harmonic test function, and each phase voltage/current harmonic distortion rate can be tested.
Suitable for 3-phase 4-wire, 3-phase 3-wire, single phase 2-wire, and 2-phase 3-wire systems with
frequency 50/60Hz.
Collects and shows 3-phase voltage, 3-phase current, frequency and power parameters.
Generator
Line voltage (Uab, Ubc, and Uca)
Phase voltage (Ua, Ub, and Uc)
Frequency Hz
Load
Current Ia, Ib, Ic A (unit)
Each phase and total active power P kW (unit)
Each phase and total reactive power Q kvar (unit)
Each phase and average power factor PF
Parameter setting function: users are allowed to set and change parameters and parameters shall
be stored in internal FLASH memory and cannot be lost even in case of power outage; most of them
can be adjusted using front panel of the controller.
Wide power supply range (8~35) V, suitable for different starting battery voltage environment.
All parameters apply digital adjustment, instead of conventional analog modulation with normal
potentiometer, improving whole reliability and stability.
Module is mounted on the 35mm guide rail.
