VDE Transformer Construction |
|
|
| |
The Global Standard series open frame linear power supplies are characterised by professional design and ruggedised construction. With input line voltage of 100 / 120 / 220 / 230 / 240V AC ±10% at 50 or 60Hz, these supplies can be used worldwide. |
The power transformer is designed with enclosed split bobbin construction and creepage distances as per VDE0730 requirements. The units have 3750V AC isolation. The global standard series are high efficiency conservatively designed units which undergo 12 hours burn-in tests before shipment. Efficiencies of over 60% reduce heat dissipation, thereby ensuring long operating life. |
Standard models are listed in Table. However special versions can be offered with output voltages between 2V and 32V DC and power output from 15 Watts to 150 Watts. |
