Description: This is a professional AC-DC Power Transformer Unit sold by HARMAN Professional, a USA Company. All factory wired. Cord included, resettable fuse on input and push button power switch. Dual bridge power rectifiers to assure no DC offset/ noise. So quiet I can not hear it running. Twin 27,000 UF filtering capacitors that look to be in parallel for an incredible 54,000 uf DC output filtering. The data-plate shows the Toroid Transformer is wound to output 21.45-VAC @ 120-VAC in. That is before load and before the DC rectifiers. So you have to multiply that by 1.4 (ac-dc bridge rectification). Plus load, outputs about 28VDC. This is a fast-response unregulated linear supply. Includes the bridge rectifiers heat-sink through-hole mounting plate. The board is hard-fused for 15amp so you would want to keep it under 10amp. This is a very powerful and well designed industrial power supply. Diameter of transformer is just under 4-1/2" and about 2" thick. Weight: 5.5 lbs. Has mounting rings and rubber damper below. Shipping: will be packaged well to assure safe transit, quick shipping.
