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

PB Design has developed a range of integrated systems that provide uninterrupted DC power for switch tripping and closing in electrical substations. The standard range of products is approved to National Grid and Network Rail standards in the UK and to equivalent international supply authority standards for worldwide use, so you can be confident that you are installing the correct product for your application.

These DC Switch trippers combined with PB Designs well proven constant voltage battery charging technology, a choice of batteries and state of the art digital controllers, ensure you are installing the best possible protection for your or your clients critical load requirements.

Standard outputs are available from 24 to 220V DC with other bespoke power outputs which can be made to order.

The integrated units are supplied in rugged mild or stainless steel cubicles or 19” racks, with standard ingress protection to IP31. Smaller wall mounted units are available where substation or plant room space is at a premium. The advanced control system incorporates digital metering of various battery parameters and a monitoring system that combines visual and audible indication with a selection of Scada interfaces for external monitoring.

PB Design has 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.
