The ES-9-24 is suited for legacy industrial control systems, telecommunications equipment, and commercial instrumentation requiring stable 24 V DC regulation from either AC line or DC bus sources. Single-phase input design supports distributed power architectures in cabinet-based installations.
– Compatibility & Integration
This model is obsolete as of March 1998. The recommended alternate part number is HWS30A-24/A; however, interchangeability is not guaranteed. Verification of form factor, connector type, and electrical behavior is required before substitution in existing designs. Availability is limited to used, refurbished, or surplus inventory channels.
