Electric Actuator & Accessories
Specs : 9
CONSTRUCTION AND PERFORMANCE:
Housing:
• Weather Proof Enclosure (cover must not be left off when
exposed to the weather or damage will occur to the unit)
Batteries:
• Two 12V 1.4AH Sealed Lead Acid Batteries wired in
series
Battery Monitoring: Local LED Indicator and (2) wire
voltage free normally open contact for remote monitoring
Battery Charging: Automatic Smart Charger
Battery Conservation: Shut-off batteries after 1 minute or
when actuator stops.
Operating Temperature: -4ºF (-20ºC) to 122ºF (50ºC) LED
light may not function below -20 ºF
Power Protection: Two 5 amp fuses. One is for the external
power output circuit and the other for the battery output circuit
Current Draw @ 24 VAC:
• BBU only Maximum 10mA standby (0.25 VA)
• Max. 420mA charging (10 VA)
Current Draw of Actuator with BBU:
• 600 lb-in - 1.9A (with Load)
• 2,000 lb-in - 2.7A (with Load)
• 5,000 lb-in - 4.1A (with Load)
Power Requirements: 24-27VAC or 30-38VDC (the
minimum voltage is required to provide proper battery
charging)
Power Output:
• BBU Output with 24VAC supply is 30-38 VDC
• On failure of AC supply, battery output is 24-25.5 VDC
Although charging will not work at -4°F, the batteries will still
hold their charge for an extended period of time as described
under shelf life.
