Product Overview
Canberra's Model 3105 supplies detector bias from a single-width Nuclear Instrumentation Module (NIM) slot, with the output set on a turns-counting dial and read on an analog meter. Lamps show whether the unit is set for positive or negative output, and the rear INHIBIT input lets a detector's shutdown line cut the high voltage.
Key Features
- Output dial marked 0 TO 5000V, set on a turns-counting knob
- Analog panel meter scaled 0 to 5 (kV)
- POSITIVE and NEGATIVE polarity lamps
- Front ON / OFF toggle
- Rear HIGH VOLTAGE output connector J1 and INHIBIT BNC input J2
- Single-width module with the standard NIM rear power connector
Applications
- A repair project for a lab that runs 3105 supplies and wants a working spare
- A parts donor for the meter, dial, lamps, connectors or front panel of another 3105
Frequently Asked Questions
Does it power up?
Yes. It powers on and makes output, and the meter agrees with the output. The fault is that the output wanders while it is being adjusted.
Is a manual included?
Not included.
What am I getting, and what am I taking on?
A used 3105 with an unstable output, sold as-is for parts or repair. The meter, dial and lamps are all present, and the photos are the spec for this unit. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
The meter still tells the truth, which is half of any repair. Whatever makes the output wander is on the other side of that panel, waiting for someone with a scope and a free afternoon.
