## Description

OONO DC 4.5-30V 10Amp Manual Blinking Flasher Module - DC Load Flasher - RELAY - Flasher : desertcart.in: Car & Motorbike

Review: Before I got my Federal Signal FC controller, I used to use these to control the on/off timing for my siren's motor when doing attack signal. Now, I use it to flash the solenoids on my mini sirens that need a 1/1 pulse timing. This little module is exactly what i needed, and is a great price. Also has two sscrew holes so you can mount it. I will be using those holes to mount it inside a cabinet along side a couple relays and a contactor for a homemade single motor 3 signal siren controller.
Review: Very easy to wire up and adjust flash rate, and relative small in size. I use it to make some railroad crossing lights flash alternatively for a man cave railroad crossing.

## Features

- This is a simple and practical blinking flasher module, the ON and the OFF duration can be adjusted separately. The blinking flasher module is suited for both resistive and slightly inductive loads. This blinking flasher module is ideally suited for driving for example LED lamps, hazard lights, warning signs, safety beacons, DC light bulbs, etc ....
- Operating voltage DC 4.5 to 30V. Maximum current: 10 Amp. Maximum load 300 Watts/at DC 30V, 120 Watts/at DC 12V. (NOTE: this product no step-up, step-down or inverter function, only for DC load)
- Time-ON 0.01 to 15 seconds and Time-OFF 0.01 to 15 seconds adjustable. The output ON - OFF - ON – OFF… cycle alternates.
- Two precise 25-turn adjustable potentiometers, you can use a screwdriver to easily adjust the ON and OFF time you need. With LED indication for output status.
- Compact plastic case and wires connects for easy mount. Two screw mounting holes are convenient for you to fix it on the wall or wooden board. Of course, you can also choose not to lock the screw.

## Questions & Answers

**Q: what is the slowest rate of flashes per minute capable with this product?**
A: If you adjust the ON and OFF all 15S, per minute 2 cycles.

**Q: any idea if this works with a 5v ebike led headlight/tailight with a 1 amp rating? I need them both to flash**
A: Connect it first to a solid state relay (SSR) then connect relay output to your headlight, make sure the relay can handle enough output current to operate your headlight.

**Q: Is this waterproof?**
A: Will it work under water?  Probably not but for normal use on a vehicle it should be water resistant enough.  I have them mounted on the fenders of my tractor.

**Q: I purchased one but the instructions are in Chinese....are English instructions available?**
