It ensures that all devices connected to W-3900 receive clean & filtered power, which reduces noise and ensures better sound and picture quality from amplifier, DJ equipment, home recording, projector, TV, computer, and other electronics..
Phase and the ground wire connection of AC source can be detected automatically.
the W-3900 circuit detects dangerous voltage irregularities and provides the highest level of surge & spike protection..
Multi-stranded, ultra-high purity 99.99% Oxygen Free Copper is used as conductor material for the best conductivity and transfer..
2-level shielding Power Cord: braided pure copper layer and aluminum foil to limit RFI and EMI interference.
double PVC jackets and extra nylon jacket..
High-quality plug with non-magnetic brass pins and solid IEC connector to provide extreme conductivity, insulation and connection. Both can withstand 15A/125V loads..

Dual-phase formula delivers double the power: cooling gel phase helps deeply hydrate and correct while cream phase helps neutralize stressors and lock....

Revolutionary dual element design represents a ground breaking transducer achievement.
Two elements (condenser and dynamic) are enclosed in a single housing.
Dynamic element delivers the aggressive attack of the beater while the condenser captures the round tonalities of the shell.
Elements are positioned in a perfect phase relationship, something practically unachievable with two separate microphones.
Robust design for enduring dependability on the road.
Integral 80 Hz HPF switch and 10 dB pad on condenser element.

Heavy duty steel frame design reduces flexing and features a superior finish and aluminum trunnion table support for long-lasting durability.
1 HP, 115V/230V, 1 phase TEFC motor with 2 speeds: 1,620 FPM and 3,340 FPM for wood and non-ferrous metal cutting.
Two-speed pulley with easy tensioning system.
Durable aluminum, rubber-coated upper and lower 9 spoke wheels are precision balanced for superior blade tracking.
Oversized 15 3/4 in. x 18 7/8 in. precision ground cast iron table with t-slot miter capability tilts 3° left to 45° right with a positive stop at 90°.

...is Smart On Grid system improves safety.
increases system reliability, and simplifies solar system design, installation, maintenance , and management..
We have improved the AC wiring solution. Configure converters for faster installation. Avoid the risk of miswiring the fire, zero and ground wires.Meanwhile, the DC input is designed with MC4 connector to avoid reversing the positive and negative terminals. (Some customers extend the solar panel cable so that the positive and negative polarity is reversed).
Grid Tie Inverter can monitor in real time the power generated by the inverter through the AC digital meter.（Voltage, current, active power, electrical energy, frequency, power factor）No fire risk and electric shock during installation and operation due to low DC voltage(up to 50V) compared with at least 200V from string inverters.
Regarding the heating problem of the inverter:this is normal phenomenon. All electronic devices generate heat during operation. The inverter uses aluminum alloy material. Metal can conduct heat better. The inverter also has over-temperature protection if the temperature is high. Then the inverter will automatically reduce the working output efficiency. Or stop working. After cooling down,....

The base of the protector adopts a rail type with two screw holes, which can be directly installed separately or mounted on the HT35 rail..
Use 5 indicators to indicate: normal, phase loss (voltage three-phase unbalance), reverse phase, overvoltage and undervoltage..
Phase loss protection means that when the protected line is in the running state or non-operating state, any phase failure occurs, and the delay is 2S..
Overvoltage protection means that the voltage of the protected line is higher than the set value, and the delay is 3~8S, and the recovery is 6~20VAC..
Reverse phase protection, a protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action..

3 INDICATORS-The protector base adopts 35mm rail type or device type, and has two screw hole structures inside, which can be directly installed separately or HT35 rail. Indicated by three indicators: normal, phase loss(voltage three-phase unbalance), reverse phase.
PHASE LOSS PROTECTION-Phase loss protection means that when the protected line is in the running state or non-operating state, any phase failure occurs, and the delay is 2S.
REVERSE PHASE PROTECTION-Reverse phase protection, a protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action.
VOLTAGE IMBALANCE PROTECTION-Voltage imbalance protection, which refers to a protective measure that will affect the safe operation of the line due to three-phase voltage imbalance.
IDEAL FOR-Widely used in air compressors, electric motors, distribution boxes, water pumps, oil pumps, central air conditioning units, etc.
