optional (see SOLAR PANEL, page 17 for more details about solar charging).
In multi-user applications the D5 operator is available with a transformer rectifier unit
(power-pack), which replaces the battery and charger. The power pack operates
directly off a 220V* mains supply only. Battery backup is available by simply adding
an externally mounted battery.
*Alternative voltage ratings are available on request
A10
Engineered for industrial and high-duty sites, the A10 is built around a precision-
machined, die-cast aluminium chassis/gearbox incorporating a self-locking gearset.
Accordingly, the unit is resistant to forced entry.
The integral electronic controller has similar functions to those of the D3 or D5 and
uses the same technology in terms of origin and encoder signal inputs. Unique to the
A10 is the high speed mode, enabling adjustable opening and closing speeds up to
30 metres per minute.
The key to the A10's outstanding torque and duty cycle lies in the three-phase
induction motor and electronic inverter that form the heart of the system. Single-
phase 220-240V AC power is converted into variable frequency three-phase power,
allowing electronically controlled soft starting and stopping of the motor.
An optional DC converter is available, containing 12V batteries and UPS type backup
circuits. This enables the A10 to continue operating for a limited period in the event of
a power failure. Another option is the theft-resistant cage, to give additional peace of
mind.
"Endurance" and "Heavy Duty" derivatives of the A10 are available to suit high duty,
and high gate mass sites respectively.
