Basler Electric BE‑6868 Power Transformer

The Basler Electric BE‑6868 (part number 5950007559202) is a high‑quality power transformer designed for voltage step‑down or isolation applications in industrial and utility control systems. It converts a primary AC voltage to one or more secondary voltages, providing galvanic isolation and power delivery to control circuits, relay panels, and auxiliary devices. The transformer is built for continuous duty with low losses and excellent regulation.

Electrical Specifications

Primary voltage: 120/240 VAC (dual tap) or 480 VAC (depending on configuration), 50/60 Hz. Secondary voltage: 24 VAC, 120 VAC, or other custom voltages. Power rating: typically 50‑500 VA (specific to model). Insulation class: Class B (130°C) or higher. Regulation:<5% from no‑load to full‑load. Temperature rise: 50°C above ambient.

Construction and Materials

The transformer features a grain‑oriented silicon steel core for high efficiency and low magnetizing current. Coils are wound with copper magnet wire and insulated with high‑temperature varnish. The assembly is vacuum‑impregnated to prevent moisture ingress and reduce noise. Terminals are clearly labelled and accessible for easy wiring. The unit is housed in a sturdy steel enclosure with mounting feet for panel or floor installation.

Protection and Safety

Built‑in thermal overload protection (optional) prevents damage from prolonged overloading. Primary and secondary windings are separated by reinforced insulation, providing isolation voltage of 2500 V RMS. The transformer complies with UL 506, CSA C22.2, and IEC 61558 safety standards. Grounding terminals are provided for safety.

Applications

This transformer is used to supply control power to protective relays, PLCs, annunciators, and lighting circuits. It is also used in motor control centers, switchgear, and battery charging systems. Its robust design makes it suitable for harsh industrial environments, including high‑humidity and temperature‑varying locations.

Installation and Maintenance

Mount the transformer on a flat, vibration‑free surface. Connect primary and secondary leads according to the wiring diagram provided on the label. Ensure proper grounding. No routine maintenance is required beyond periodic inspection for loose connections and cleaning of ventilation openings. The transformer’s insulation resistance should be checked annually.

Reliability and Quality

Basler Electric’s BE‑6868 transformer is manufactured under strict quality control, including hi‑pot testing, turns‑ratio verification, and core loss measurement. It is designed for a service life of over 20 years under normal operating conditions. Basler provides full technical documentation and support.

Conclusion

The Basler Electric BE‑6868 power transformer is a reliable, efficient, and safe solution for voltage conversion and isolation in critical control systems. Its high‑quality construction and proven performance make it a trusted component in power distribution and protection applications.
