Dual Output EI60 Low Frequency Transformer PCB Mount 380V 400V To 24V 19V
Dual Output EI60 Low Frequency Control Transformer, 380V/400V to 24V & 19V, 24VA, PCB Mount
This EI60 low frequency transformer is a UL-recognized (File No. E332338) step-down control transformer designed for industrial equipment that runs on a 380V -500V AC three-phase or line-to-line supply. It delivers two independent isolated secondaries — 24V/0.6A and 19V/0.5A — from a single unit, so one transformer can feed both a control circuit and an auxiliary/logic circuit without adding a second power supply.
Built on a laminated EI60 silicon steel core with a vacuum-varnished bobbin and solid copper windings, it offers low no-load loss, low temperature rise and stable output under continuous duty. The through-hole PCB mounting pins (input 1-3-4-5-6 / output 9-10 and 15-16) allow direct board soldering, saving wiring harness cost and assembly time.
- Dual isolated outputs - 24V/0.6A + 19V/0.5A from one core, replaces two separate transformers.
- Wide input tapping - 380V / 400V / 415V / 500V taps cover EU, Middle East and Asian industrial grids with one part number.
- UL recognized construction - File No. E332338, built to meet safety-critical OEM requirements.
- PCB mount design - rigid through-hole pins for automated soldering and vibration resistance.
- Full copper winding - lower copper loss and better thermal stability than CCA alternatives.
- Fully customizable - voltage, VA rating, pin layout, bobbin and terminal configuration made to your drawing.
