(AVR) Automatic Voltage Regulators: Accessories
Power Factor Controller
Controls and maintains a required power factor condition whilst running in parallel with a mains supply. This unit also incorporates a voltage matching facility for use with basic automatic synchronising equipment.
APM Alternator Protection Module
Detects under and over voltage without current transformers. The relay output can be used to trip main circuit breaker, de-excite the alternator or stop the engine.
DFD Diode Failure Detector
Protects the machine against damage caused by failure of the rotating rectifier diodes.
Dual AVR Automatic Voltage Regulator
Two hard wired MX321 AVRs with a manual change over switch. Reduces down-time in the event of AVR failure.
MVR Manual Voltage Regulator
Allows manual control of the machines excitation and therefore the output available from the main terminals. Provides manual control of output voltage.
FDM Frequency Detection Module
Adjustable upper and lower speed limits, a reliable method of disconnecting an engine starter and providing over speed protection.
ELM Excitation Loss Module
Monitors the excitation to the generator. On loss of excitation an output relay is energised, can be used to initiate alarm or protective device.
RCI Remote Control Interface
Allows the remote control of AVR’s or PFC’s using industry standard control signals.
