Product Description

SD series electric actuator introduced Bernard technology

1.Components:

Its major components are imported. The parts processing, components selection, the whole machine assembly all are carried out strictly according to the process and technical requirements.

2.Low price:

It has the same function of Origenal Bernard actuator, but it's cheaper.

3.Standard (unstandard can be costomized)

The whole machine test strictly conforms to national standard. 

 4.Features:

SD series electric actuator has multiple functions, steady quality, high precision, various specification and light weight. It is safe and reliable. It is flexible and convenient to modulate and install.

5.Usage:

It plays an important part in industrial process control system and is widely used in electricity, metallurgy, petrochemical, building materials, heating, light industry, and water treatment.

 

 

Our product advantages:

 

 Cut-off signal protection

The actuator stop at the original, all-on or all-off position which is instructed by users as the signal is interrupted by accident or the input signal is less than 3mA (called the cut-off signal) in order to guarantee the whole system's safe and stable. It also possesses the output connection point for alarm.

Over-torque of two- way protecting function

When the torque exceeds the setting scope, the torque switches inside the actuator and outputs a signal to the controlling circuit for stopping the motor to protect the valve, the driving parts and the motor. After the mechanical over-torque fault is relieved, shutting down the power supply or input an instantaneously reversed signal, the actuator will come back to turn normally.

 Auto switch function

The actuator can implement three kinds of switch function – "Distant- automatic / distant -manual /local". It can also operate electrically and manually on the spot.

The pros and cons of switch function

The control panel program has the pros and cons of switch function that satisfied different situations on-the-spot.

 Dynamic braking

The control panel program of modulating model electric actuator has the dynamic braking function that can prevent motor's inertia movement and ensure the stability and reliability of the controlling system. 

Servo-motor with double protection and high-efficiency 

All the motor has the thermal and open-phase protecting function. When there is an unexpected failure, it will shut off the power supply effectively so as to protect the motor. It serves as a good servo characteristic and it will not overheat after frequent movements.

Stronger anti-interference function

With the imported main chip of control panel and stable performance, the actuator has the stronger anti-interference capability. The input and output signal adopt the shielded wire.

 

Technical parameters

1.The input signal: 4--20mA DC

2.The input resistance: 250 ohm

3.Input passage: 1
4.Basic error: 1%, 2.5%

5.Deviation: 1.5%

6.Deadline:  0.5%--3% continuously adjustable

(according to the indication of system)

7.Damping characteristic:  No-oscillating

8.power supply: three-phase 380V~50Hz, single-phase 220V~50Hz  for selected, other voltagec can be costomized.

9.Working conditions: Temperature:  Integral-type -10°C-- +55°C, separate-type -25°C -- +70°C                  

Humidity: ≤85%The surrounding air does not have the corrosive elements  
10.Protection grade: it conforms to the IEC145 IP65 standards. (Excluding the separate-type GAMX with waterproofing and dustproof functions fixed in rooms), bus type and intelligent type IP67.

11.The cut-off signal protection: It can be divided into all-on, all-off and home position according to your instructions.
