When measuring low voltage light sources, an external low voltage power supply is essential.

Viso light measurement systems all work fine with external DC power supplies. Any low voltage power supply can be used. Just type your settings into the Viso software

If you want full integration with the Viso “Light Inspector” software you may use one of these compatible power supplies. For these type, Viso interfaces exist and settings are communicated automatically to the Viso software.

An external power supply is especially handy if your mains supply is not very stabile. Further, some incandescent light sources are very sensible toward mains voltage fluctuations.

Viso LabPower (coming soon)


Viso light measurement systems have built in power analyzers that will give all power details: Wattage, PF, DPF etc.

Some clients prefer their own power analyzer. If you want full integration with the Viso “Light Inspector” software you may use these compatible power analyzers.

GW Instek GPM-8310 is a digital power meter for single-phase (1P/2W) AC power measurement. Features include DC, 0.1Hz~100kHz test bandwidth, 16bits A/D, and 300 kHz sampling rate. It adopts 5” TFT LCD screen with a five-digit measurement display and provides 25 power measurement related parameters, and has a high-precision measurement capability.

Most Viso accessories connect to your PC with USB cables. With a full range of accessories (such as LabFlicker, LabTemp and LabTarget) being close to your measurement system (LabSpion/BaseSpion) you might like to run all communication with both the light measurement system and all accessories through the same USB cable to your PC.

For this setup we recommend:

1. NEDIS USB Hub, 8 ports – QC3.0 – USB 3.2 
– Mains Powered – USB Powered – 5 Gbps USB 

2. USB 3.0 Active booster Extension cable – 20 m
– USB 3.0 and backward compatible
– Data transfer up to 5 Gb/s
– USB A male to USB A female
– Power supply included

3. USB 3.0 cable – USB-A male to USB Micro B male – 5 m
Data transfer up to 5 Gb/s
