- CSA certified (File # LR3902) and UL recognized (File #E207860)
- RoHS and REACH compliant
The 160H20 is a low voltage, vertical PC board mount power transformer with a universal dual 115/230V primary rated for 50/60 Hz. Rated 24 VA, it is intended for higher-current board-mounted supplies for control, audio, instrumentation and embedded equipment sold into 115V and 230V regions.
The secondary is made of two windings. Connected in series they deliver 20V C.T. @ 1.2A; connected in parallel they deliver 10V @ 2.4A. The 20V center-tapped secondary is one of 20 output voltages the series offers between 5 and 120VAC RMS.
The 24 VA size is the largest rating in the 160-161 range and is non-concentric wound. The 160 series mechanical table lists overall dimensions of 1.63 x 2.25 x 1.38 in (A x B x C), 0.02 x 0.04 in pins and dimension E of 2.10 in; shipping weight is 0.8 lbs (0.36 kg). The single 115V primary, 60 Hz version is 161H20.
Construction uses a split bobbin with low primary-to-secondary coupling, so no electrostatic shield is required. Insulation is Class B (130 degrees C) and hipot tested to 2,000V RMS. The series is CSA certified (File # LR3902) and UL recognized (File #E207860), and this part is listed as RoHS and REACH compliant.
Ideal For
- 24 VA PC board mounted power supplies
- Center-tapped or parallel low voltage secondary supply
- Equipment designed for both 115V and 230V mains
- Control and electronic circuit boards needing an isolated AC supply

Frequently Asked Questions
What output does the 160H20 provide?▾
Its two secondary windings give 20V C.T. @ 1.2A when connected in series, or 10V @ 2.4A when connected in parallel. The transformer is rated 24 VA.
Can the 160H20 run on 230V?▾
Yes. It has a universal dual primary rated 115/230V at 50/60 Hz.
Does it need an electrostatic shield?▾
No. The split bobbin design has low primary-to-secondary coupling, so no electrostatic shield is required.
What certifications and insulation ratings apply?▾
The series is CSA certified (File # LR3902) and UL recognized (File #E207860), with Class B insulation rated 130 degrees C and a hipot of 2,000V RMS. The part is also listed as RoHS and REACH compliant.
How big is the 160H20?▾
The 160 series mechanical table lists overall dimensions of 1.63 x 2.25 x 1.38 in (A x B x C) for the 24 VA size. Shipping weight is 0.8 lbs (0.36 kg).
