Power supply Q&A
Q: Why JCHENG SECURITY write these Q&A?
A: At first ,we don’t want to sell power supply in AM, cause it is super low profit. But we intended to sell more professional security surveillance equipment in AM. To effectively reduce the defective rate of security surveillance equipment, we decide to sell our own power supply. Junk quality power supply not only damage your facilities, but also may cause terrible accident. Don’t penny save and pound loss.
Q: How to tell a good quality power supply?
A: Generally, there are 3 type of power supply in AM as per our survey.
Rank 1—Junk level. Those are made by the second-hand circus board. Through repairing and change to the new housing, they are sold by the cheap price. If for security surveillance camera system, which require the 24H*7D working, it would be damaged easily and also damage the camera.
Rank 2--Average level. Those are made by the new boards but with cost down way. They made by small factories in China who survive from its price advantage. It is ok to use for 1 or 2 year under standard power supply systems. Compare to the Rank 1, they are with quality improved and with longer usage life. It is maybe a good choice for customer concerns on price only. However, if you want to get cost down products could only make a fortune to select from thousands of sellers on AM.
Rank 3—Qualified level. Those are made by the new boards and all the products should be with certificate. For the US, the required certificates for electricity are FCC, ROHS or UL. For EU, required certificates are CE and ROHS. The products which have certificates means the products are tested through the American or EU Authorized Lab and with the strict producing standard process.
Q: How about JCHENG SECURITY’s Power supply?
A: Except the item DR120100AE belong to the rank 2, for rests we listed are all with certificates and it is below to rank 3.
