- 40 VA at 400 Hz from a 115 VAC primary
- Series secondary: 20V C.T. @ 2A
- Parallel secondary: 10V @ 4A
- Epoxy cast to withstand shock and severe environments
- Two coil design: balanced windings, low magnetic radiation, no electrostatic shield
- PCB mount, 1.05 in max height, 0.05 in (1 mm) pin diameter
- 45 C temperature rise, 6% regulation
The 227N is a 40 VA, 400 Hz power transformer from the 227 Series, designed to mount on a printed circuit board and run from a 115 VAC primary. Its secondary is rated 20V C.T. @ 2A with the windings in series, or 10V @ 4A with them in parallel, giving designers two output options from one part.
The 227N is a 400 Hz model rated 40 VA: 20 V centre-tapped at 2 A, or 10 V at 4 A in parallel, with 6% regulation.
The transformer is epoxy cast to withstand shock and severe environments. A two coil design provides balanced windings and low magnetic radiation, so no electrostatic shield is required.
Per the series table, the 227N stands 1.05 in high (max) with a pin diameter of 0.05 in (1 mm); shipping weight is 0.37 lbs (0.17 kg). Temperature rise is 45 C and regulation is 6%. The part is RoHS and REACH compliant, and it is classified under UNSPSC 39121301.
Note: the manufacturer states that the 226-227-228 product line will soon be discontinued as a stocked series and is available while quantities last.
Ideal For
- On-board 20V centre-tapped or 10V supply for 115 VAC equipment
- 400 Hz PCB-mounted power conversion
- Circuit boards exposed to shock or severe environments
- Replacement of an existing epoxy-cast PCB transformer
