Waterproof Transformers

A. Overview
An isolation transformers is external potted and is suitable for places with high humidity such as underwater and river banks.

B. Features
The waterproof transformer has the characteristics of high power efficiency, low loss, low temperature rise, and has good cost performance.

C. Design Consideration
1. Low temperature rise
2. High work efficiency
3. Low operating loss
4. Thermal protection and short circuit protection
5. Shield isolation between the Primary and Secondly
6. Waterproof rating
7. Low vibration and noise
8. International Power Transformer Safety Standards
9. Power 10VA to 1KVA

D. Temperature resistance and product temperature rise
Typically we design that over ambient of 25°C, the temperature rise is below 50℃, or suit.

E. Compliance Standard
IEC61558 waterproof rating IP67

F. Design required parameters
1. Input voltage (V)
2. Working frequency (Hz)
3. Output voltage (V)
4. Output current (A) or output power (W)
5. Transformer installation space
6. Transformer installation and connection method
7. Requirements of temperature resistance level, efficiency, power consumption
