BROADCOM AFBR-S4KPEBIAS SiPM Bias Source for WB-Type and WL-Type
Description
The Broadcom® single silicon photomultipliers (SiPM) bias source powers all
AFBR-S4K silicon photomultipliers. It is an ideal addition to the SiPM
evaluation kit and can be used with any single SiPM or SiPM array.
The active area of these SiPMs is 3.0 × 3.0 mm2 with single-photon avalanche diode (SPAD) pitches of 15 μm, 35 μm or 47 μm. The WL-type series stands for high efficiency and improved low noise performance. Its excellent timing enables easy replacement of PMTs, APDs, and PIN diodes.
Safety
This document contains some information and warnings which have to be followed
by the user to ensure safe operation and to retain the instrument in a safe
condition.
The SiPM Bias Source is intended for evaluation purposes only. It has been
designed for indoor use in laboratory environment for a temperature range 5°C
to 40°C, 20% to 80% RH (non-condensing). Do not operate while condensation is
present.
Use of the AFBR-S4KPEBIAS Bias Source in a manner not specified by these instructions may impair the safety protection provided. Do not operate it outside its rated supply voltages or environmental range.
When the Bias Source is connected to its supply, the Bias Output is live. Opening the covers or removal of parts exposes live parts. It must be disconnected from all voltage sources before it is opened for any adjustment, replacement, maintenance or repair which may be only carried out by a trained person who is aware of the hazard involved.
CAUTION! This product is intended for evaluation purposes only. Therefore, it is to be handled only by trained personnel in a laboratory environment.

Front and Rear Panel Connections
The front and rear panels with their corresponding controls are shown in
Figure 1 and Figure 2. As soon as the Bias Source is powered the green Power
On LED lights up and the Bias Output is switched on.
The bias voltage is set with a screwdriver at the potentiometer and can be
measured with a multimeter to adjust the required value.
The Current Limit LED is only lit in case the set current limit is reached.
All controls can be switched while the power is on.
