- UL listed (# E207860) Type 3AH and CSA certified (# LR209651); RoHS and REACH compliant
The 265Z5 is the 450 VA model of the 265 Series low-voltage, filament high-current transformers, supplying 5 V center-tapped at 90 A from a dual 117/234 VAC primary. It is the part in the series ordering table flagged with 5 kV insulation, which makes it the option to look at when a heavy 5 V winding needs added insulation.
The ordering table lists the 265Z5 as the largest single-secondary model (450 VA) and marks it "* 5kV Insulation". The primary is a 117/234 VAC, 50/60 Hz dual primary, so the transformer can be applied to equipment running on either line voltage. The secondary is rated 5 C.T. at 90 A RMS, giving a center-tapped 5 V winding for heavy filament or low-voltage loads.
Construction is open style on a 4 hole frame for chassis mounting, with minimum 6" long leads or copper tabs with holes. A dual bobbin design means no electrostatic shield is required, and Class B insulation (130 °C) is used. Units are hi-pot tested at 2,000V RMS, and this model is listed with 5kV insulation.
For compliance, the 265 Series is UL listed (# E207860) Type 3AH and CSA certified (# LR209651), and the 265Z5 is listed as RoHS and REACH compliant. Identifiers include UPC 623980186085 and UNSPSC 39121301.
Ideal For
- 5 V C.T. filament supply at up to 90 A
- High-current low-voltage AC supply where 5 kV insulation is specified
- Chassis-mounted equipment fed from 117 VAC or 234 VAC mains
