AN EMPLOYEE OWNED COMPANY
Your long term trusted partner.
PB Design design and manufacture industrial DC charging systems, typically battery tripping units (BTU), intertrippers, or DC telecoms backup for use within substations, either within the utilities network or within a plant room. The battery charger ensures the uninterrupted operation of essential electrical systems within the substation in the event of a power outage. The absence of an electrical supply can lead to equipment damage and potential harm to personnel. Therefore, DC charger systems are of the utmost importance in providing the necessary energy to control protection devices, enabling the safe isolation of electrical faults.
Based in Clevedon, North Somerset, England, our capabilities run from design through production, testing, installation, commissioning and maintenance. We can supply either standard or custom-built products designed to meet customer or industry-specific needs. Our commitment to customer care is reflected in an enviable level of repeat business from an ever-expanding customer base, including many “blue chip” organisations.
