    Whelen Edge 9000 wiring

    +12 to BLUE and/or GREEN should enable lamps as per Page 7 of Whelen's instruction sheet

    Whelen Edge 9000 wiring

    I don't think the UB412 would fit correctly in an old EDGE. It is designed for the Ultrabar/9U series. Check out these - or better yet, if you can find and "EB6", here are Whelen's instructions for upgrading older EDGE 9000s. It might help. Your measurements indicate the possibility of a bad...

    Whelen Edge 9000 wiring

    Unfortunately, I think there's something wrong with the power supply. It should have flashed as the wiring is pretty simple. I believe the relay you hear clicking was a "cutout" that would limit flashing to only two outlets. There seems to be a thin yellow wire coming from underneath the...

    Whelen dashmiser2 with issue

    I haven't ran into the symptoms you describe so this is just a guess - maybe the voltage regulator on your board is no good (given different behaviors on different power sources). Attached are pics of a dashmiser PS I had lying around. What's really weird is your description of it getting...

    Whelen CSP690 Xenon Bulbs to use?

    FWIW, here's what happens if the inverter isn't turned off!

    Whelen CSP690 Xenon Bulbs to use?

    :) you might want to start with the '507 patent. The designer leveraged a neon lamp to sense when desired anode voltage was achieved. The power supply is working feverishly between flashes to "accumulate" the target anode voltage which, by the way, is why you need to be REALLY CAREFUL to avoid...

    Whelen CSP690 Xenon Bulbs to use?

    One of the greatest sources of information for this stuff are the patents from the engineers who created it in the first place. google US3515973, US4013921, US4321507, US5013973 and definitely keep an eye out for ANY Xenon discharge patent from Scott Sikora (Tomar) too. Also google "Don...

    Whelen CSP690 Xenon Bulbs to use?

    Also according to the attached, the CSP690 does not have output regulation while the UPS690 does.

    Whelen CSP690 Xenon Bulbs to use?

    I use these: https://www.xenonflashtubes.com/trigger-coil-transformer/zs-1052-1-trigger-coil-transformer-1052v-12kv_49.html#techsheet but my re-tubes are just for restoration of old stuff - I can't tell you how they'd perform in a professional situation. Pins 1&3 connect to ground Pin 2...

    Whelen CSP690 Xenon Bulbs to use?

    The headlight flasher's control depends on which actual model it is. After puzzling over your "black-box" pic, I googled and found https://www.k-bid.com/auction/4847/item/13 which looked pretty similar. However this is a BL2150A which is part of a 2-wire "B-LINK" network controlled via serial...

    Whelen CSP690 Xenon Bulbs to use?

    FYI - Here's an off-brand tube dissected to show the trigger coil.

    Whelen CSP690 Xenon Bulbs to use?

    I think your black box may be a Whelen headlight flasher. This device doesn't play any role in your CSP690 strobe system but I'm wondering if all you really need is a replacement hide-a-way/hide-a-flash strobe tube. Search "whelen HAW" in eBay. You'll see what I mean (trigger coil built in).

    Whelen CSP690 Xenon Bulbs to use?

    Given both a UPS690 or CSP690, whatever you plug into them, they will need a trigger coil to flash. The trigger coil takes the trigger pulse from the power supply (on the white wire usually) which is ~200+ volts and transforms it to ~4K or more to ionize the Xenon gas within the tube. I'm _not_...

    Whelen CSP690 Xenon Bulbs to use?

    Cool but what you're getting is just a raw tube. You'll have to put a trigger coil in there somewhere. Are you hip to that? For instance, here's some old Whelen aircraft heads I re-tubed. There's a trigger coil in there that needs to deliver that "4kV" pulse to cause the ionization in the tube.

    Whelen CSP690 Xenon Bulbs to use?

    I just hooked up a CSP690 and measured 557 volts with no tubes connected - certainly sufficient to fire your tube :)

    Whelen CSP690 Xenon Bulbs to use?

    I think the worst that could happen is that your 50-watt lamp wouldn't even flash. I don't think you could cause harm to the CSP690 because it has circuitry in place that will stop charging the capacitors when they've reached their maximum anode voltage at the conclusion of a charge cycle (with...

    Wanted Whelen MPC01 Controller (Pre-Programmed)

    In my opinion, for the purpose of bench-testing, I think your best bet is to: a) ask Whelen for a copy of "SC Programmer" (assuming you have windows PC?). (They sent a copy to free-of-charge last year after a simple email asking for it, FWIW) b) Obtain a RS232-RS485 converter (search this site...

    Whelen ST8RRBB Liberty LFL

    The manual states, "Without BL627 Siren Amplifier: Splice the BLUE and GREY wires from the lightbar to the BLUE and GREY wires in the 4-conductor MPC cable." You shouldn't need a BL627 just to test the lightbar. But you do need an MPC01 (or 02 or 03) configured for the lightbar. There's a...

    Whelen 8029

    Just spent the last couple of days getting these two characters to flash again. One had the same part number as yours, "4A13D11518-41". Interestingly, the circuit board seems virtually identical to Whelen's aircraft strobe PS model "A413A,HDA,DF-14". The aircraft PS had bigger capacitors...

    I love the theme of clear outer optics with colored filters inside. Good luck buffing the outers. She's going to look beautiful when you're done. Pls keep the pics coming! Tx!

    That is really cool! But is that a VPPS6C (comet flash) power supply in the speaker chamber?

    Wanted Whelen 3302 power supply - preferably dead.

    I'm interested in obtaining the circuit guts of an old Whelen 3302 (ca 1980). Should be similar to a conventional 1200 power supply but drives two heads with an alternating double-flash pattern. DOA no problem - as long its physically intact. Thx!

    How to make Generic Whelen Transporter for B-Link & Smart Messenger

    @five0fan - can you provide the exact device model number? I see its made by dtech but it looks like the model-specific info is on printed on a label on the side. I'm wondering what its power requirements are...i.e. does it need +5V but you're powering it with +12? The serial line (two wires)...
