Genset Controller Units
Microprocessor genset controllers and monitoring systems that display RPM, frequency and hours, protect the engine and alternator, and run AMF logic to start the genset when mains power fails.
KG 541
KG 541
A complete genset auto controller with every input and output a DG set needs, made to suit KOEL make DG sets.
Line Voltage Monitor (LVM)
Watches mains or genset voltage and trips a relay when it goes too high or too low, protecting your equipment.
GMS 541
Genset Monitoring System (GMS 541)
A full genset monitoring and AMF controller with 5 digital inputs, 4 analog inputs, 5 relay outputs and RS 485 communication.
GMS 543
Genset Monitoring System (GMS 543)
Our larger genset controller with 8 inputs, 8 relay outputs, mains voltage measurement and an events log.
Engine Safety Units
Engine safety units and hour meters that watch oil pressure, temperature, fuel and speed, give clear fault indications and shut the engine down safely when something goes wrong.
Engine Safety Unit ER
A compact engine safety unit that detects 6 faults, with a built-in charge lamp, LOP bypass timer and a 70 Amp contact.
W Point HR Meter
Hour meter and RPM display that reads engine speed from the charging alternator W-point, with over and under speed relay.
HR01
HR01
Engine hour meter with RPM display and built-in over and under speed relay, field settable on site.
HR Meter
A compact hour meter and RPM display with a built-in over speed relay.
Display Units
Rugged round digital indicators for engine temperature and fuel level, with IP65 protection and tested to IEC standards for harsh engine-room conditions.
Digital Temperature Indicator (4-20mA Current I/P)
A rugged round digital temperature gauge for engines with 4-20 mA sensors, sealed to IP65.
Digital Temperature Indicator (Resistive I/P)
A digital engine temperature gauge for standard resistive sensors, sealed to IP65 and built for vibration.
Digital Fuel Level Indicator (4-20mA Current I/P)
A round digital fuel level gauge for 4-20 mA level sensors, sealed to IP65.
Digital Fuel Level Indicator (Resistive I/P)
A digital fuel gauge showing 0 to 100% for standard resistive level senders, sealed to IP65.
Relay Cards
Relay and interface cards that connect controllers to starter motors, stop solenoids, contactors and sensors, with LED indication, resettable fuses and back-EMF protection.
Interface Card White
A positive-switching interface card that neatly connects the genset to its controller, with fuse and back-EMF protection.
2 Way Relay card
Two changeover relays with LED indication on one compact 12 V DC card.
Start Stop Relay card
Heavy-duty start and stop relays with LED indicators, rated up to 70 Amps.
GMS Relay Card
Five relays for Start, Stop, MC, GC and Hooter in one card, matched to genset controllers.
Battery Chargers
Wall-mounted battery chargers that keep genset starting batteries charged, with under and over voltage protection and reverse polarity protection.
Charge Lamps
Compact charge lamps that show at a glance whether the charging alternator is working.
Magnetic Pickups (MPU)
Magnetic pickup speed sensors in many lengths, threads and cable options, with single and dual output, stainless steel bodies and auto-grade connectors.
