BWM/TE-30 High-Power Street Light Electromagnetic Voltage Stabilizing Power Saving Controller

 BWM/TE-30 High-Power Street Light Electromagnetic Voltage Stabilizing Energy-Saving Controller is available in two types: indoor type, installed at the lower end of the indoor lighting control cabinet; outdoor type, which can be installed according to user requirements. It is widely used in public lighting environments such as municipal roads, highways, bridges, tunnels, gardens, docks, landscape lights, sports squares, amusement venues, advertising light boxes, etc. Applicable lamp types include high-pressure sodium lamps, low-pressure sodium lamps, metal halide lamps, high-pressure mercury lamps, fluorescent lamps, and all gas-discharge lighting fixtures.

Technical Features
1. Contactless Voltage Regulation Technology: Provides rapid automatic compensation for grid overvoltage and undervoltage, delivering a sinusoidal voltage to the load. Rated voltage, energy-saving voltage levels, and ramp-up/down voltage adjustments are completed instantly within approximately 0.1s, ensuring that lighting equipment neither extinguishes due to sudden low voltage nor burns out due to high voltage.
2. Full Chinese LCD display, capable of setting multi-period voltage regulation and stabilization: voltage stabilization and energy saving in the first half of the night, voltage and current reduction for energy saving in the second half.
3. The device dynamically tracks input voltage and automatically adjusts energy-saving levels to keep lamps operating under constant voltage, ensuring normal operation and achieving energy-saving effects.
4. Dynamic adjustment range: Different types of discharge lamps, different operating stages, and different adjustment ranges fully avoid lighting interruptions caused by excessively low voltage.
5. Controllable starting voltage (200V): Using an electronic voltage reducer (non-reactive) reduces the lamp's starting overcurrent by 40%, extends lamp lifespan, and avoids efficiency loss.
6. Soft start: Regulated voltage ensures that the light source is protected from high-current impact, reducing the failure rate and extending lamp lifespan.
7. Reset function: After power failure, the device restarts automatically and resumes the preset operating state.
8. Three-phase regulation: Each phase is independently regulated, with strong operability and the ability to handle three-phase unbalanced loads.
9. Sinusoidal wave output, no harmonics, and no harmonic distortion in the output.
10. Communication interface configuration: Equipped with an RS485 interface and corresponding communication protocol.

Installation and Debugging Instructions

BWM/TE-30 High-Power Street Light Electromagnetic Voltage Stabilizing Energy-Saving Controller installation requirements: Assemble electronic components on a 150×150 universal circuit board according to the circuit diagram, while the photoresistor is installed on the distribution iron box panel and connected to the circuit board with insulated flexible wires. The thyristor, insulating board, AC contactor, and automatic air switch are all installed in a 600×800×200 distribution iron box. The thyristor must be equipped with a heat sink, sufficient heat dissipation space, and ensure insulation from the box.

Usage Precautions:
1. Ensure the main unit and auxiliary equipment of the power device are intact.
2. The oil tank, iron core, and clamp external grounding wires of the power device must be reliably grounded.
3. All valves should be in the open state.
4. The bushing should be grounded, the general cap at the top of the bushing should be well-sealed, and connections to external leads should be secure and coated with power grease.
5. The oil level in the oil conservator and capacitor should be normal, and the gas collection box of the diaphragm-type oil conservator should be free of gas.
6. The oil level of the on-load tap changer should be slightly lower than that of the power device's oil conservator.
7. Vent all elevated parts to ensure they are completely filled with power device oil, and the gas relay should contain no residual gas.
8. The adsorbent in the breather should be sufficient, without discoloration or moisture, with good oil sealing to ensure normal breathing function.
9. The position of the tap changer should meet the operational requirements of the equipment, and all switches should function flexibly.
10. The thermometer should indicate correctly, and the set values should meet requirements.
