Liebert E-007BS Transformer
When you are dealing with a critical power failure in a Liebert environmental control system, you need an exact OEM replacement transformer to restore 24V control power. The Liebert E-007BS Transformer is a 75VA-rated component specifically engineered for industrial HVACR applications requiring a high-voltage step-down. This unit accepts a flexible primary input of 440V to 490V PRI and delivers a stable 24V SEC output, making it the standard for precision cooling equipment that utilizes specific 460V or 480V line voltages. As a veteran technician, you know that using a generic control circuit transformer can lead to secondary voltage fluctuations that trip sensitive microprocessor boards. The E-007BS ensures voltage regulation and current limiting that meets original manufacturer specifications. Whether you are replacing a burnt-out 75VA transformer or performing a preventative upgrade during a system overhaul, this part provides the electrical isolation and reliability required for continuous-duty Liebert units.
Key Benefits for Technicians- Precision Voltage Conversion: Engineered for 440-490V primary inputs to provide a consistent 24V secondary control signal.
- Optimized 75VA Capacity: Sufficient volt-ampere rating to handle HVAC control circuits, contactors, and relays without overheating.
- Liebert Compatibility: Direct E-007BS E-007B replacement ensures mounting footprints and terminal locations align with existing high-performance cooling systems.
- High Dielectric Strength: Built with robust insulation materials to withstand the harsh electrical environments found in data centers and industrial plants.
- Can I use this if my supply is exactly 480V? Yes, the 440-490V primary range is specifically designed to handle standard 480V industrial three-phase legs common in Liebert deployments.
- What causes these transformers to fail prematurely? Most failures are due to secondary shorts in the 24V circuit or excessive heat from poor cabinet ventilation. Always verify your total VA load before commissioning.
- Is this compatible with the older E-007B model? Yes, the E-007BS is the current technical standard and direct replacement for legacy E-007B units.
