Comparative Adavantage of ZRSUNS Laser Power Supply
|
| | ZRSUNS Laser Power Supply | Normal Other Laser Supply |
1 | metal Box | Aluminum oxide metal box, good thermal conductivity, highly polished, hard wearing, touch smart and good view. | Iron sheet with paint |
2 | screws | Screws with nickel-plated and higher hardness, salt spray test up to 48 hours, not easy to rust and to be stripped. | Normal screws, easy to rust and distortion under big pressure |
3 | silicone tube | Industrial grade silicone tube to wrap high-voltage cables, this type silicone tube containing a high proportion of silica, good insulation performance, against moisture, hard wearing, protected high voltage effectually. | Cheap silicone tube is easy to shoot-through when spark |
4 | Radiator Fan | Original Taiwan Delta brand or ADDA brand, famous brand, model 8025 flow rate ≥50CFM, model 9225 flow rate ≥60CFM, the life time is more than 70000 hours under room temperature. The good quality and steady performance. | Copy brand radiator fan, flow rate low, not good radiator |
5 | FBT (Flyback Transformer) | High voltage diode 25KV, 30mA, high voltage capacitor 30KV, high voltage coil withstand 7KV, quality materials warranty. | Most is less this level, cost is just lower half than us |
6 | Radiation Fin | Radiation fin work surface thickness 5MM, 80W power supply radiation fin weight ≥220g, 150W power supply radiation fin weight ≥300g. | Thickness 2-3MM, the weight < 200g.150w radiation fin weight <270g. |
7 | The US Regulations Terminal | The US regulations terminal (connecting pins) metal materials is nickel-plated copper (not included nail), fasten to connect, not easy to oxidize. | No |
8 | Thermistor | Thermistor made in Taiwan, withstand higher load and big current, good quality and steady. | cheap one, cost is lower half than us |
9 | Protector Tube (Fuse) | Used US brand Littelfuse, explosion proof, stable quality and reliable performance, effective protection circuit. | Normal new brand |
10 | Safe Capacitor | Safety capacitor original imported from Japan. | No |
11 | Filters | Filter inductance ≥6ml, wire diameter 0.75mm, effectively suppress the interference of the power grid. | Small |
12 | VARISTOR | VARISTOR imported from Germany brand EPCOS (Siemens), reliable quality. | No |
13 | Rectifier Bridge | Rectifier bridge imported from Japan, 15 ampere | Normally 6-8 ampere |
14 | Power Module | Power module is US Fairchild power chip. | Copy brand or some Chinese brand |
15 | Rectifier diode | Rectifier diode is Japan brand Shindengen. |
16 | Transistor | Transistor IC adopt US brand TI or Fairchild. |
17 | Power Tube | Power tube is original Japan brand Fuji Electric |
18 | Filter Capacitor | Filter capacitor is all adopt Japan brand Rubycon, BlackGate, Nichicon etc. |
19 | Film Capacitor | Film capacitor is Japan Panasonic, or Xiamen Faratronic |
20 | High Voltage Connector | High voltage connector is US GE brand plastics, High pressure, corrosion resistance, effectively prevent the high voltage ignition. | Not high pressure, easy to spark |
21 | Hardware connectors | Hardware connectors is gold-plated copper, good contact, strong electrical conductivity, not easy to oxidize. | Normal copper |
22 | Sealing Cap | Black high pressure sealing cap is silicon rubber, good sealing, and preservative, good insulation. | Looks same, but in fact not |
23 | PCB board | PCB board is FR-4, epoxy glass fiber sheet, good insulation, high mechanical strength, copper foil thickness ≥70μm, big current. | copper foil thickness ≥35μm, can not stand big current |
24 | High Voltage Cables | Red high voltage cables is 40-50KV, GB Standard, good insulation, high pressure resistance. | Red high voltage cables is 30-40KV, no GB standard |
25 | Electric Relay | Electric relay is original Omron. | Most is other Chinese brand |
26 | Solder | Solder is 63 degree, high levels of lead. | Solder is 50 degree |
