VAr Load Sharer. 415/480V 5A. The T4900 is designed to control a generator operating in parallel with the grid, or a generator operating in parallel with other generators (which are also controlled by T4900 units). The T4900 will continuously measure and compare the reactive current on the generator to an external DC reference signal connected to the “parallel line” input. The T4900 will increase or decrease the voltage of the generator (through the AVR) if it finds the reactive current level to be either too low or too high. Two built-in relays provide the increase and decrease pulses for the automatic voltage regulator (AVR). The strength (width) of the pulses is proportional to the voltage deviation. The E7800 Motorised Potentiometer can be used to adapt the contact pulses to a signal suitable for most AVR’s.

Load Sharer. 415/480 VAC 5A. The T4400 is designed to control a generator operating in parallel with the grid, or a generator operating in parallel with other generators (which are also controlled by T4400 units). The T4400 includes built-in frequency control and an optimized regulation scheme. These two features provide near perfect stability and compensates for any drift within the speed controller. A soft load/unload facility is also included.

Electronic Potentiometer. 230V AC. The T7900 Electronic Potentiometer is typically used as an interface between a unit that provides increase/decrease contacts signals and electronic speed governors or voltage regulators (AVR) controlled by analogue voltage or current signals. The T7900 works much like a conventional motorized potentiometer (e.g. the E7800). However, instead of a variable resistance, the T7900 provides a variable voltage (e.g. -5 to +5 VDC), current (e.g. 4-20 mA) or a pulse width modulated signal (PWM). The voltage and current range is programmable. The PWM output provides a 500 Hz signal with programmable duty cycle. The analogue outputs are galvanically isolated.

T3000 Frequency Relay. 100/110V. The T3000 is intended for effective frequency surveillance on generators, busbar or other distribution systems. The relay contains the functions “under frequency” and “over frequency” time delayed, and 2 individual output relays, one relay for each function.
