I am attempting to determine the trigger voltage of the Sunpak 522 external flash. Doe anyone have an idea? Thanks in advance for your help.

I'd avoid this model for cameras that require lower trigger voltages.

It's been reported at up to 190 volts (although I found one report of a bit over 10 volts, most user reports show higher voltages):

You can measure a specific strobe yourself. See instructions here:

The newer models like the Sunpak 544 (only around $129.95 brand new from B&H and even less used), or the Sunpak 555, have lower trigger voltages better suited for modern cameras without voltage protection (although a number of models will allow trigger voltages up to 400 volts via PC sync cord attached strobe).

Hi Jim-

Many thanks for the link. It appears that the Sunpak 522 has a trigger voltage of between 170 and 190 volts. Too high for me.

Grab a Wein Safe unit (around $50 USD). My 522 measured 194V (a whopping 220V with the remote sensor). The Wein Safe reduces to about 6.5V. Or pick up a Sunpak 544...they measure @ 6.5V out of the box.

For the 522 I'd still use a Wein-Safe unit. They have models for both hot shoe & PC connection. My 522measured 194 V at it's PC connection (and a whopping 224 V at the remote sensor hot-shoe, if you happen to have one of those)!

Dear stowaway7!

With my lovely Dynax 7D "DON"T needed any "Wein" or similarly adapters, as the PC sync accept till 400 volts trigger voltage, & the Sunpak 522/3600 is much less that the maximum allowed.

Best wishes,
