Product Profile of Open Frame Linear Power Supplies
Aplab limited offers open frame linear power supplies. The product open frame linear power supplies are characterized by professional design and ruggedised construction. With input line voltage of 100 / 120 / 220 / 230 / 240v ac ±10% at 50 or 60hz, these open frame linear power supplies can be used. Aplab limited is an iso 9001-2000 certified company. The power transformer of the open frame linear power supplies is designed with enclosed split bobbin construction and creepage distances as per vde0730 requirements. The units have 3750v ac isolation. Open frame linear power supplies series are high efficiency conservatively designed units which undergo 12 hours burn-in tests before shipment. Efficiencies available are over 60 percent reduced heat dissipation, thereby ensuring long operating life. The unique features of the open frame linear power supplies:
- Input voltage options for all countries
- Available with industry standard sizes and mounting
- 12 hours burn-in facility
