Products Description
Features:
1. Select the aluminum bracket and APS plastic shell, small volume, light weight
2. Use permanent magnet synchronous motor with magnetic hysteresis clutch mechanism, has related self-protection function
3. Suitable for a variety of control signals: incremental (Floating point)
Voltage (0-10V), current (4-20mA)
4. With a 0-10V or 4-20mA feedback signal (optional)
5. Drive gear adapt metal gear, greatly improve the service life of the drive
6. Low power consumption, large output power, low noise
7. Body has cast copper, cast iron, cast steel, stainless steel, a variety of materials to choose from, to suit different working media and temperature requirements
8. The body has two types of threaded and flanged connections, convenient installation
9. This system is suitable for the air conditioning system air winter/summer temperature control unit
By the temperature sensorTE-1, TC 1 pid temperature controller and electric two-way valve of TV-1 supply air temperature control" System, installed on the air supply pipe of TE-1 to the temperature of the detected signals to TC 1, will TE by TC-1 of values compared
with the set value consistent, consistent output signal at the same time, the opening of the continuous control TVTVTV-1 is adjustable Eventuallykeep TE-1 measurement of ambient temperature in setting temperature range .
When the coil temperature is lower than a certain threshold, low temperature protection switch to cut off the motor power, TS-1 so that fresh air valve closed, to prevent the coil water freeze, coil up to crack .
