Company Info

 

specification: 1.BESN's electronic ballasts are high-tech products which is both environment friendly and significant in energy saving. It greatly reduces the cost in power supply circuit, stabilizes the lighting,and is for general power supply; while with its multi-protecting function, and high safety , it greatly prolongs the lifespan of tubes or bulks. Obviously, this product greatly improves the quality of illumination, and reduces the operation coast. As an economic and applicable ballasts, it is the ideal upgraded products to replace inductive ballasts. 2.technic specification Rated voltage of power supply AC220V Rated frequency of power supply 50Hz Total energy saving e30% Tolerable Frequency of power supply 40Hz~400Hz Ambient temperature -30~+40 Static consumption d1W 3. installation and wire connecting It's better for the wire of output be vertically adown to the earth. The wire connecting doesn't require the distinguish of polarityexcept for DC electronic ballasts for low sodium lamp, whose red wire connects with the anode ,and the black wire with the cathode. At the input end, two pieces of wires connects with the power supply, while at the output end, two pieces of wires connects with the lamp bulk/tube; plastic twist wire of 0.5~0.75m is available for use(should also meet the specification of installation) 4. notice and alert The case of BESN's electronic ballasts is heat emiting, so around it relevant space is required. The max temperature of the case is 80; the storage temperature is -40~+90. When it is starting up, the voltage between the output wire and the earth is thousands of volt, so insulation is very important here. Fuse or automatic switch with 3~5times of the input current is required to be in series with the input wires. When the ballasts is works wrong, don't open it yourself .Exchange it at the suppliers' or send it through the supplier to the manufacturer for guaranteed repair. Because of its triggering attribute, the ballasts cant be connected with trigger or match the bulbs/tubes with triggers. The type and watt of the bulb/tube should match the ballasts. Warrant of repairing: one year. 5. sketch map for installation
