Spang Power Electronics, a recognized technology and application expertise leader, provides heavy-duty DC power supplies, or rectifiers, for powering a variety of industrial applications. These DC power systems take continuous AC “voltage in” and provide controlled / variable DC “voltage out”. DC power systems typically consist of a voltage matching / isolation transformer coupled with SCR bridges packaged in an enclosure that usually includes circuit breakers, metering and pilot light indication.
For over 50 years, Spang has been perfecting power supplies through field use under rugged conditions and diverse applications. Realizing that a DC power system which does not deliver peak performance year in and year out will cost customers considerable profit, Spang designs each power system for the highest quality and reliability. Spang’s highly experienced engineering teams design DC power systems to withstand even the harshest of environments.
Spang provides DC power systems for all types of unique industrial applications including:
- Hypochlorite Generation
- Mill Duty Cranes
- Particle Accelerators
Spang applies a variety of rectifier technologies and topologies in support of these industrial applications including:
- 6, 12, 18, and higher pulse rectification
- Regulated output
- Unregulated (brute force) output
- SCR and diode based designs
- AC SCR based "auto-tapping" with output DC rectification
- High-frequency IGBT based designs (SMPS or DC chopper applications)
- Special ripple filtering utilizing inductive and / or capacitive filtering
