Electrical
Dedicated weatherproof electrical power and controls panels shall be situated at the end of the unit and contain:
● Separate, fully accessible, controls compartment, allowing adjustment of control set points whilst the unit is
operational.
● Circuit breakers for protection of all major unit components.
● Separate, permanent supply for controls/trace heating, 230V/50Hz/1Phase 16Amp. (max permanent cable size
4mm²).
The electrical power and control panel is wired to the latest European standards and codes of practice. A mains supply of
400V 3PH 50Hz, permanent supply of 230V 1PH 50Hz and control circuit of 24V/230VAC shall be accomodated.
Power Factor Correction
When applied to the motors of each compressor, the compressor power factor is controlled to a minimum operating value
of 0.95 at the full operating capacity. This satisfies many supply authorities that may impose surcharges on equipment
with power factor less than 0.95. (available on units UCCL085, UCCL100. UCCL125, UCCL150).
Electronic Soft Start
The electronic soft start enables the compressor’s motor to be ramped to speed with the minimum full load current.
Further benefits include removal of nuisance tripping, supply voltage dips and motor overheating.
Ultracap Uninterrupted Power Supply
The Ultracap module is an external backup device for the EVD Evolution used to close the valve in the event
of mains power failures. The module guarantees temporary power to the EVD Evolution in the event of power failures,
for enough time to immediately close the connected electronic valve. It avoids the need to install a solenoid valve in the
refrigerant circuit or use the battery backup module.Ultracap storage capacitors (EDLC = Electric Double Layer
Capacitor), which are recharged independently by the module. Ultracap capacitors ensure reliability in terms of much
longer component life than a module made with lead batteries: the life of the Ultracap module is at least 10 years. In
addition, not using lead batteries also means no special precautions are required regarding safety and pollution.
Power Monitoring
A power meter shall be fitted to the unit. Voltages, currents and power inputs can be monitored and recorded giving
power usage of the chiller. Current transformers are fitted to the unit’s incoming supply.
