Control Signal:Modulating
Dimensions:6.28 in L x 3 in W x 3.3 in H
Electrical Connection:3 ft, 18 ga Plenum Cable with 1/2 in Conduit Connector
Enclosure Type:NEMA 2, IP42, UL Enclosure Type 2
Frequency Rating:50/60 Hz
Humidity Rating:95% RH Non-Condensing
Input Impedance:100 kOhm for 2 to 10 VDC 0.1 mA, 500 Ohm for 4 to 20 mA
Noise Level:<62 dBA Fail-Safe
Power Rating:2 W Running, 1 W Holding
Temperature Rating:-22 to 122 deg F Ambient, -40 to 176 deg F Storage
Timing Range:95 s Constant, Independent of Load Running Motor, <25 s at -4 to 122 deg F, <60 s at -22 deg F Fail-Safe
Torque Rating:22 in-lb
VA Rating:4 VA
Voltage Rating:24 VAC/VDC
- The actuator is mounted directly to a damper shaft from 1/4 in up to 1/2 in Dia by means of its universal clamp, 1/2 in shaft centered at delivery
- A crank arm and several-mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft
- A 2 - 10 VDC feedback signal is provided for position indication
- The TF Series actuators provide true spring return operation for reliable fail-safe application and positive close-off on air tight dampers
- The spring return system provides consistent torque to the damper with, and without, power applied to the actuator
- The TF Series provides 95 deg of rotation and is provided with a graduated position indicator showing 0 - 95 deg
- The TF uses a brushless DC motor which is controlled by an application specific integrated circuit (ASIC) and a microprocessor
- The microprocessor provides the intelligence to the ASIC to provide a constant rotation rate and to know the actuator's exact fail-safe position
- The ASIC monitors and controls the brushless DC motor's rotation and provides a digital rotation sensing function to prevent damage to the actuator in a stall condition
- The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. Power consumption is reduced in holding mode
- Class 2 power transformer source
- Electronic throughout 0 - 95 deg rotation overload protection
- Actuators are double insulated electrical protection
- 2 - 10 VDC, 4 to 20 mA with ZG-R01 (500 ohm, 1/4 W resistor)
- 2 - 10 VDC, 0.5 mA maximum position feedback
- Reversible with built-in switch direction of rotation (motor), reversible with CW/CCW-mounting direction of rotation (fail-safe)
- Visual indicator, 0 - 95 deg(0 deg is full spring return position) position indication
- 95 sec constant, independent of load running time (motor)
- UL94-5VA housing material
- Maintenance-free
