flx+CHARGE Overview

DC Switch Tripper/Battery Charger

  • Thyristor (SCR) based for high reliability and long design life (>20 years)
  • Output voltages: 24, 30, 48, 60, 110, 220V
  • Single or three phase input supply
  • Current ratings from 2A to 300A
  • Suitable for Vented or Valve Regulated Lead Acid (also referred to as Sealed Lead Acid), Vented Nickel Cadmium and Valve Regulated Nickel Cadmium batteries
  • Microprocessor-based alarm controller with text display for:
    • Voltage
    • Current
    • Error log
    • and more …
  • Optional battery string monitoring for peace of mind

Dual Charger Configuration

For added peace of mind, flx+CHARGE can be configured in a dual charger configuration.

For critical applications, flx+CHARGE can be configured as a dual charger. Each charger will take care of charging the batteries. Should a charger fail for whatever reason, the other charger is on hand to continue charging the battery and supporting the standing load.

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 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 Design’s 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 indications 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.
