40 VA, PF 0.5
Power consumption
Standby (with 70%
holding torque
11VA, PF 0.3
Inrush current (worst
case)
During start-up the inrush current might be high. See
chapter 7.1
for
more information. Eltorque can also assist with experience data for
product types and fuse selection.
Duty performance
According to AN 15714-
1 / IEC 60034-1
Class A – 10 cycles per hour/S2 – 15 min.
Endurance
According to EN 15712-
2
Classes A and B – 10 000 cycles per lifetime.
Cable glands
Up to four M20 glands allows serial connection of power supply and
signal wiring. Use IP68 (10 m 72 hours) glands for all wires.
Communication
Interfaces options
CANopen
allows positioning and other extended control of the
actuator. The absolute maximum theoretical number of devices allowed
on the bus is 127, but the actual number of nodes is limited by the
baud-rate and the cable quality. Eltorque recommends a maximum of
80 nodes on 500 m/1660ft cable.
Digital
2 DI (Open-Close) and 3 D0 (Open-Close-Alarm).
Analog
Al (Set position) A0 (Feedback position) and D0 (Alarm) (4-20
mA) AI/A0 signal.
Position sensor
Resolution: 360°/12bit = 0.35156°/bit
Integral Non-Linearity (INL): typ. ± 0.8°
Differential Non-Linearity (DNL): ± 0.176°
Output shaft accuracy: 1%
Position feedback not corrupted by power outage.
Configuration
USB connection to PC with Eltorque E3C. Special configuration cable is
needed, see
E3C User Manual
.
Configurable parameters
Open and Closed positions. Actuator speed, torque and valve position
regions. Inverted IO or bus parameters depending on the applied
communication interface.
Manual operation
Standard feature using fixed hand-wheel. Mechanical valve position
indicator. No need for external tools.
Cover of hand-wheel
Can be removed and refitted without tools. Protects mechanism against
mechanical damage and foreign objects. The actuator must not be
lifted by the top cover.
Self-lock
The QT50 is equipped with a mechanical self-locking device that locks
the valve to the target position when the actuator movement command
is completed
