The SITAS 4AM3242-8EN00-0EA0 is the 24V-secondary companion to the 8ED40-0FA0 (230V secondary), sharing the same three-position multi-tap primary: 575V, 550V, 525V. For machine builders exporting to Canada where 575V is the standard industrial voltage, to Northern Europe where 550V is common in heavy industry, and to marine applications where 525V generator output is typical, this transformer provides a single part number that covers all three destinations with a simple tap selection at commissioning.

24V for Modern Control Systems

The 24V secondary at 2.63A aligns with the dominant control voltage in contemporary automation: PLC power supplies, safety relays, distributed I/O, and HMI panels all expect 24VDC (derived from the 24VAC transformer secondary via a rectifier and smoothing). The 190VA short-time rating provides the surge capacity for multiple contactor coils energizing simultaneously, while 63VA continuous handles the steady-state load of the control system and all energized contactor holding coils.

Shared SITAS Platform

The core electrical and mechanical specifications are identical across all 63VA SITAS models: EI 84/28 laminated core, 86×98×90mm, screw/tab terminals, 85% efficiency, 8.4% uk, II0 vector group, 50/60Hz, thermal class B, IP00. This standardization simplifies panel design — the mounting footprint and heat dissipation are constants regardless of which primary voltage variant is ultimately installed.
