ELECTRICAL CHARACTERISTICS
Electrical Outputs
POWER SUPPLY
Mains supply: This unit runs off a 240 volt 50 hertz single phase outlet.
The controller draws 30 watt at 240 VAC.
The internal transformer reduces the 240 VAC to an extra low voltage supply of 24
VAC. The internal transformer is fully compliant with AS/NZS 61558-2-6 and has been
independently tested and judged to comply.
ELECTRICAL POWER SUPPLY:
Input 24 volts 50/60Hz
ELECTRICAL OUTPUTS:
Maximum of 1.0 amp
To solenoid valves:
24 vac 50/60Hz 0.75 amps max
Note:
up to 3 valves per station on the inbuilt model
To the master valve/pump start:
24 vac 0.25 amps max
Note:
Transformer and fuse capacity must be compatible with output
requirements
OVERLOAD PROTECTION:
Standard 20mm M-205 1 amp fast blow glass fuse.
POWER FAILURE:
The controller has permanent memory so the data is always backed up even with
the absence of all power, however to maintain the real time clock as current, a 9 volt
block battery should be installed. This will keep the clock time for extended periods
without mains power.
WIRING:
The output circuits should be installed and protected in accordance with wiring code
for your location.
