PB Design Uninterrupted DC supplies have long been approved for use in National Grid, Distribution Network Operators (DNOs), Water Authorities, Network Rail infrastructure and London Underground applications along with many other high specification projects.

  • Constant-voltage battery chargers provide low maintenance and high availability
  • Modular alarm system includes Scada interfaces for easy control integration
  • Choice of Vented or Valve Regulated Lead Acid (VRLA – also referred to as Sealed Lead Acid or SLA) and Vented or Valve Regulated Nickel Cadmium batteries to cover all applications
  • Designed and manufactured in Clevedon to UK and international supply authority standards

PB Design have developed an impressive range of highly integrated, modular systems that provide uninterrupted DC power for switch tripping and closing in electrical substations.

Utilising high frequency switch mode technology, these SMPS based battery chargers provide a compact high power density design in a 3U 19” rack that is easily installed in any 19” based cubicle. Power is provided by compact rectifier modules that can be supplied in an N+N configuration to offer redundancy within your or your clients’ critical DC system.

Hot swappable design means they provide easy maintenance of the charger system during its installed life whilst also offering the capacity to grow as the power requirement increases without having to install new and expensive replacement chargers.

24V, 48V and 110V DC options are readily available.

The state of the art control system incorporates digital metering of all battery parameters and a modular alarm system that combines visual and audible indications with a selection of SCADA interfaces for external monitoring.

Options available are:

  • Integrated or external DC distribution

PB Design have installed and commissioned its DC switch tripping/closing systems in electrical substations around the UK and worldwide for the past 40 years, in environments ranging from equatorial deserts to arctic tundra. The systems have justifiably earned a reputation for the highest reliability, availability and performance levels, even in the most hostile of environments.

PB Design is recognised as a leader in the design, manufacture and application of standby power systems. Since its foundation in 1979, the company has developed a leading edge range of battery chargers and uninterruptible power supplies covering a full range of AC and DC standby power requirements.
