| Model number |
PST-DC2920L DC/DC Converter |
| Country of origin |
USA, NAFTA eligible |
| Function |
Switchmode voltage reducing
converter |
| Input voltage range |
6 VDC to 34 VDC (this converter
will only reduce the voltage, so the input voltage must be at least 10% higher
than the output voltage that is set) |
| Peak output power |
60 Watts (limited to 5 amps
output, so at 1.5V the maximum power would be 7.5W) |
| Peak output current |
Up to 5 Amps output |
| Output voltage nominal |
User or factory adjustable
single output 3V-12 Volts |
| No-load overhead |
10 to 30 mA is drawn from the
battery when no load is connected, see chart below |
| Connectors |
Input connector is a 5.5x2.1 mm
barrel socket
Output connector is a 5.5x2.5 mm barrel socket
The two
included cables are identical, with a 5.5x2.1mm barrel plug on one end and a
5.5x2.5 mm barrel plug on the other end.
The cables are 16AWG zip cord and
20 inches long. |
| Voltage adjustment |
User adjustable by means of a
pot accessable from the outside of the case, see diagram below |
| Line regulation |
± 0.5% |
