Model AVA Universal Power / VSD Controllers
Speed control of most single phase PSC motors with mechanical loads such as fans, centrifugal pumps or
those applications where the torque of the load varies with speed. Can also control shaded pole and
universal motors with any type of mechanical load. Remote stepless power control of all general resistive and
inductive loads such as lamp, heating elements or transformers. Multiple & dissimilar loads can be
accommodated simply by connecting in parallel.
Phase angle control of AC mains. B version – single output for small PSC motors connected as 2-wire,
universal and shaded pole motors, lamps, heaters and transformers. D version – dual outputs for small,
medium and large PSC motors and all other types of loads that require main & auxiliary control outputs.
Standard proportional control via 0–10 V or 2-20ma DC control signal.
Single phase 240 V AC ( 10/

AVA5.0 – 1200 VA 5A
Main variable output rated to full rated power and can be varied between ~20 and 100%.
Auxiliary output is zero voltage solid state switched and can be rated up to 100% rated power. Total
controlled plus auxiliary output power should not exceed 100% of maximum controller rated power.
Environmental: up to 50 C in free air for AVA5.0 & AVA8.0 (no de-rating required). For AVA10.0 to
o
AVA20.0 de-rate (max VA) 1.6% x "max VA rating" per
Surge protection network incorporated on board for over voltage / noise spikes. Control circuit for remote
control signal operates at 12 volts DC and is totally isolated from the supply mains / load power circuit by a
double insulated fully encapsulated BS415 rated transformer and a 5000V opto coupler between control
input & power output. Generous power design parameters – controller designed for PSC motor starting and
reasonable short term overload conditions. On-board replaceable fuse in ~L line. External DB MCB
overload / isolation protection recommended for motor load is usually adequate to protect controller.
0-10 volts terminals B (+ve) & C with input resistance 1 Mohm. 2-20ma on terminals B (+ve) & C with sink
resistance = 500 ohm. An internal 10V DC source (max 50 ma) is provided between terminals A(+) & C
which can be used for custom remote control applications, a remote or local potentiometer or testing.
At low control levels, the controller is designed to shut down the main control and auxiliary outputs. Normal
operation resumes at higher control levels. Auto turnoff occurs at < 0.8 VDC for voltage input, ~<5% for a
potentiometer, < 1.5 ma for 2 - 20 ma.
Fitted with internal Electromagnetic Interference suppression network, and complies with AS/NZS CISPR
14.1:2003 when correctly installed. ACA C-Tick lev 2 N29529.
