- Filaments: 6.3Vct @ 2.25A and 5V @ 4A
- 120 VAC, 60 Hz primary per the ordering table
- Horizontal ("Z") mounting style
- Class A insulation (105 degrees C), Hi-Pot tested at 2,000V RMS
- Run full wave bridge or full wave C.T.
- REACH and RoHS compliant
The 290HBZ is an 84 VA plate and filament power transformer from the 200 Series, listed in the horizontal ("Z") mounting table. It supplies a 620V centre-tapped high voltage secondary at 150 mA, a 6.3V centre-tapped filament winding at 2.25A and a 5V filament winding at 4A, making it a candidate for tube equipment that needs both a plate supply and heater/rectifier filament supplies.
Its ordering-table primary is 120 VAC at 60 Hz. Hammond notes that most of the "Z" mounts do not follow the series' 115V / 125V lead-selection choices, and directs users to each part's drawing for its available primary voltages, so check the 290HBZ drawing before wiring the primary.
Dimensions from the horizontal-mount ordering table are A 3.00 in (76 mm), B 3.75 in (95 mm), C 4.00 in (102 mm), G 1.50 in (38 mm), H 4.50 in (114 mm) and J 3.75 in (95 mm). Series construction features include minimum 6" long leads, Class A insulation (105 degrees C) and a Hi-Pot test of 2,000V RMS, and the series is described as CSA certified (209651).
According to the series data, 200 Series units can be run full wave bridge or full wave C.T. The 290HBZ is also listed as REACH compliant and RoHS compliant, with UPC 623980397849 and UNSPSC 39121301 for purchasing records.
