This module is intended to supply the heaters of indirectly heated tubes. Their supply isn't half as critical as the supply of directly heated tubes. Why this module? It is compact, very low drop, does the full job from AC in to DC out over a range from 2.5V to 10V. It is able to supply a stable 1.5A 6.3V DC voltage from a 6.3Vac winding !
|
| PURPOSE |
|
TentLabs heater supply is designed to supply the heaters of indirectly heated tubes. Its' main use is feeding phono and linestage tubes, to keep the hum levels down.
|
| TECHNOLOGY |
The heater supply uses Schottky barier diodes for rectification. They provide clean switching and inhibit low voltage drop. 2 filter capacitors (4.700uF each) smooth the voltage. A discrete design, low drop voltage regulator feeds a power transistor at the output.
A tenturn timmer allows for accurate adjustment of the output voltage.
|
| APPLICATION |
| More tubes can be connected in parallel, assumed their respective heaters are at equal potential. If heater potentials are different, separate modules (and transformer windings for each module) are required. The heater reference needs to be connected close to the tube The total output current is limited to 1.5Adc, mainly due to heat dissipation.
The units are factory adjusted at your order. After installation, the supply needs no adjustment.
|
| PRICING & WARRANTEE |
The cost is £25.00 each +VAT+carriage. Specify DC voltage when ordering. 5 years of warrantee is valid for the filament supplies, assuming they are build in according application information.
|
| SUPPORT |
The modules are provided to you populated with easily seen connectors. All you need to do is wire up the AC input and the regulated DC output, you may need to trim the output DC voltage. Support is given at info@hificollective.co.uk or call us on 01908 217202. A very straight forward module to use.
|
| SAFETY |
Though this is a product which if handled properly is save, it is surrounded by high voltages. Working with high voltages requires safety measures and professional behavior. HiFi Collective Ltd takes NO responsibility for accidents resulting from improper usage or handling.
