What is a Thyristor Controller?
Conventional burst-firing control of heater loads results in
fairly large temperature swings in both the heater itself and the
thyristor junction switching it. Full-cycle control is a method of
distributing energy to heaters evenly and at the same time keeping the
thyristor junction temperature at a reasonable level. The
RN.F.. 'SOLITRON' series from Carlo Gavazzi is designed to eliminate the problems
of interfacing BMS (Building Management System) or other analogue output controllers to solid state
relays (Thyristors) in heating applications. The innovative A/D
input circuitry enables full-cycle control of the heater load with linear transfer.
Acceptable control inputs are 4-20mA (RN.F.I)
or 0-10Vdc (RN.F.V). The voltage-controlled versions require a 24VAC/DC
auxiliary supply whilst current controlled versions require no external
supply, being loop-powered.
The benefits over conventional systems include:
Easy installation
Reduced wiring
Lower cost
Space saving
Reduced electromagnetic emissions.
To ease ordering and installation even further this series is available
in both 1 pole and 2 pole versions.
How does it work?
The analogue switching relay provides a number of full cycles, evenly
distributed over a fixed period, depending on the control input. The
input of the 4-20mA or 0-10 Vdc respectively corresponds to zero and
full output within a period of 1.28 secs @ 50Hz (1.07 secs @ 60Hz).
This principle makes the transfer characteristics fully linear. the
principle operates with zero switching, thus ensuring a reduced level
of radiated and wire-conducted noise. The 2-pole type has alarm LED
indicator by loss of master phase.
The analogue Full Cycle Switching is not recommended for lighting
control due to light flickering.

| By using a modular approach to thyristor control the
designer can produce small, cost-effective Heater Battery Control from a
0-10v DC signal. CSE offer a specially designed signal converter ( EVF-1 )
to be used in conjunction with the Carlo Gavazzi solid-state relays for this
purpose. One signal converter can drive up to two 'solitron' relays These
can be utilised to achieve kilowatt ratings up to 85kW - please
contact CSE for details. |
