FUSING & WIRING:
It is recommended to use
semiconductor (fast acting) type
fuses or circuit breakers
(Semiconductor - MCB) for unit
protection. On initial ‘switch on’
some loads may need an increased
Factor of Safety (F of S) for unit
and/or device protection. (See the
SRA Datasheet for further
information).
Installation and maintenance of this
equipment should be done with
reference to the current edition of
the I.E.E. wiring regulations
(BS7671) by suitably
qualified/trained personnel. The
regulations contain important
requirements regarding safety of
electrical equipment (For)
International Standards refer to
I.E.C/ directive IEC 950).
FEATURES
• Infinitely variable 0-98% output.
• Minimum Set Speed Adjuster
• Single hole fixing.
• Rugged and compact.
• Large triac for inrush protection.
• Integral RC Snubber
• Integral EMC filtering
DESCRIPTION
This compact variable phase angle regulator is of open construction and is suitable for 230V operation, driving up to 3Amp single phase
mains driven inductive loads, such as induction motors, fans & pumps. It gives fully adjustable voltage outputs from zero to maximum.
The controller has an integral RC Snubber network for control of inductive loads and a Minimum Set Speed adjuster (multi-turn cermet) to
allow the designer/installer to fix a minimum output voltage level to prevent a motor being driven too slowly.
An integral choke/capacitor RFI circuit enables to controller to meet current EMC standards for emissions.
The large Triac enables the unit to handle high inrush currents with ample safety margin on industrial installations. An adhesive backed silver
label and hairline knob, are optional extras, for front panel mounting.
APPLICATION
Suitable for most simple mains driven motors & fans
