Waterproof toroial transformer with plug Application:


 

The following dimension is for the plastic cover of the encapsulated transformer,the

 

model No. delegate different power(:eg: H-200 means for 200VA toroidal transformer.)

The  Outdoor waterproof Transformer in black colour  is rated 105VA-2000VA for devices 105VA-2000VA watts or less

 

Grewin' s garden waterproof  transformers are light weight, highly energy efficient water-safe making them ideal for outdoor lighting & Christmas lights.

 

  • Splash Proof protection from water in all direction
  • Approved safe with IP64 Rating for outdoor use
  • Approval number with NSW Department fair trade.
  • Fully water proof fuse designed to eliminate the possibility of an electrics shock (as defined in IEC standards 65 and 257)
  • Included is a special safety fuse which eliminates the possibility of electrocution.
  • GWET-105 means 105VA in black cover and Australia plug .The power range is between 105VA and 2000VA.

B.Dual 110V Power Transformer:

For the international market request, these types of the GREWIN Transformers are designed into dual primaries for 110V. No matter what about your local voltage is 110V or 220V, you should use them. Below are the methods for using:
1. If you are using 110VAC(such as Taiwan, US), Please parallel the two primaries 110V. Please pay attention to the terminals of 110V must be short circuit, and the terminals of 0V must be short circuit.


2.If you are using 220VAC(such as Hongkong, China Mainland, Europe), Please series the two primaries.  Please pay attention to one terminals of 0V must be short circuit with another terminals of 110V.

 

3.GREWIN has various kinds of state-of-the-art equipment, which are used in production, sampling and testing. Our equipments enable us to produce good quality products efficiently.
