PWRgate Battery Backup DC Power Switching System Power Pole Amateur Ham Radio

Description

Power Gate Battery Backup Automatic DC Power Switching System
What this does is automatically switch any load (13.8 vdc up to 30 amps) from your normal power supply to your battery when the power supply or AC power fails.
There are some products out there using solid state devices that are subject to losses, heating, failure and cost up to 0!!!
Why do you think the other guys use a massive heatsink on their solid state product? Because they need to dissipate heat. HEAT = POWER LOSS!
This system does not suffer from any of those problems.
FAST SHIPPING! IN-STOCK, we ship same or next business day!
Designed for 13.8 VDC (11-15 volt type) equipment, such as radios, accessories, lighting, etc
Maximum current 30 amps can be operated and switched
Has Anderson Power Poles on all three connections (power supply, load, battery connections).
Would you prefer no Power Pole connectors or perhaps ring terminals for one or more of the connections?
No problem, just do the buy it now and tell me what size bolt for ring terminals (up to 5/16 bolt) and which color wire set (PS, load or battery wires) to have PP or ring or plain wire
How to use this:
A typical use would be that you have an Amateur (Ham) radio station that you want to have automatic battery back up switching.
Connect
YELLOW
wire set to YOUR 13.8 VDC power supply DC output (like the Samlex SEC-1235M that we sell here on eBay)
Connect
BLUE
wire set to your load (radios, repeater, etc that run on your 13.8 VDC power supply)
Connect
RED
wire set to 11-15 YOUR battery
Has mounting tab if you wish to mount it.
When your power supply fails or AC power fails to your power supply, the relay automatically switches your load (radios, etc) to your battery. When AC power to your power supply returns, the relay then switches back to operate your equipment on the power supply as normal.
Note: this is a relay with less than 10 ms switching time. Some radios may interpret this momentary loss of power and restart.
Remember, the alternative is much more expensive, so you decide whether saving lots of money is worth this small caveat, you understand and accept this.
Also remember, a power failure happens very infrequently, so why spend more than you need to to accomplish the job?
Simple, inexpensive and it works! Get two or three for all of your 13.8 VDC up 30 amp needs.
It's a simple design but lots of work to put together. To make this, we strip 11 wire ends and professionally crimp 6 Anderson Power Poles, insert into the plastic ends and then connect the grounds. You get a lot for this price!
There is no battery charging with this system, most guys prefer their own charging system and we did not add that because we don't know what type of battery you will use. Just use a float charger that is suitable for the battery you are using.
