Can you tell me what voltage the Metz 45 CT 5 Flash Gun requires at the socket on the side of the grip - to use as a mains powered device. (studio) Presume it is DC and more than 7.2 Volts! Do you have pin connection data for polarity. I intend to make my own psu if possible.
I have a circuit diagram for the 45CT-5 and the flash unit as well. The voltage is 360V DC, which goes straight across the flash tube. The top pin is positive, when the notch in the socket is on the right hand side, i.e. towards the back of the flash.
I'm also looking for a circuit diagram for a 45CL-4, if you know anyone who has one.

Raise the tiltable head the number is embossed below it(at chin side).Near hinge. That means if you tilt flash head fully upward the number is exactly at the opposite side of Flash power calculator dial(Two inch round chart).
The trigger voltage of the 45CL-1 is about 12V, so it should be safe to connect directly to the hot shoe with an adaptor, or to the pc soclet, if the D90 has one. If the D90 is anything like my Canon 40D, which can stand about 30V on the hot shoe, then all the 45CL series will be ok, as they have trigger voltages between 9V and 12V. The 45CT-5 has a trigger voltage of 15V and works well on the 40D. I use 3 different Metz 45 models with my 40D and all work well on automatic, where the flash sensor itself controls the light output.
I had that same problem also, but mines was temporarly. Ik think the condensor inside the Metz has to regeneratie (recover) itself by using with a full charged fresh batteries. The high freq. sound is normal. (although not to loud) after a 5 MINUTES the orange bulb should light up. How more u used how better the start-up time. My old Metz start-up time was around 40 sec. and now ot is within 7 sec.
Originally the 45CT1 had high trigger voltage. In the production period Metz improved it to a much lower voltage release circuit. Metz homepage (metz.de) holds the information, from which serial number on have 45-CT1s low trigger voltage. However, even the high trigger voltage was lower than 200 volts, thus safe for your Fuji.

Hey eck1960, This flash should be safe to use on your nikon d200 since I believe this flash is rated to 14.8v of flash voltage, and the d200 can take up to 250v of flash voltage. That being said this flash is not compatible with Nikon’s iTTL flash system and you are going to lose a lot of functionality with this flash. Sincerely, Allan Go Ahead. Use Us.
