Description

SBW-S、DBW-S series intelligent numerical control (microcomputer type) compensated AC power regulators are based on the perfect combination of traditional high-power compensated voltage regulators and modern intelligent control technology, allowing users to enjoy the reliability and convenience of parameter setting and maintenance brought by modern advanced control circuits, highlighting the safety, stability Energy saving and humanization of man-machine interface. The regulated power supply can be equipped with a variety of intelligent interfaces to realize the functions of "remote signaling, telemetry and remote control".

Features

• Delay output function (add output contactor).

• Lightning protection device: it can provide good surge protection in case of instantaneous change of power grid and induced lightning stroke.

• EMI filtering device: it can effectively filter the harmonic interference of power grid.

• Phase sequence and phase loss protection function.

• RS485 interface: realize remote control, remote signaling and telemetry function.

It can be widely used in industrial and mining enterprises, scientific research, posts and telecommunications, military, railway, transportation, hospitals, elevators, bowling equipment, air conditioners, hotels and other places with high requirements for power grid power supply.

The normal operating conditions of sbw-s and dbw-s series intelligent control (single chip microcomputer control) complementary AC power regulators are:

• temperature:-15°C - 40°C.

• Altitude：less than 1000m.

• Relative humidity：＜90%.

• The relative humidity installation site shall be free of gas, steam, chemical deposition, dust, dirt and other explosive and corrosive media that seriously affect the insulation strength of regulated power supply.

• The installation site shall be free from serious vibration and turbulence.

• Any special use conditions that do not meet the above provisions shall be determined through consultation with the user and our factory.
