Failed car battery, harness coupling, jump-starting or even just switching the AC unit – nasty voltage spikes can occur anywhere, anytime! The built-in gas-discharge tube is an elegant, clever solution. Usually, this gas, secured within a tiny glass tube, does not conduct electricity. However, when a high voltage is applied, the gas becomes ionized, enabling a new low-resistance path for the excess voltage to flow. Excess voltage that otherwise might have fried your devices!

Another layer of protection is the TVS: transient voltage suppressor semiconductor. This combination of layers protect your devices from extreme voltage spikes. We’ve also added active polarity protection, so that your devices stay safe even if you apply the power in reverse by accident. Additionally, there’s a built-in low-pass filter to block all unwanted impulses, and a standard fuse for extra protection.

The output voltage can be easily modified via jumper position, but there’s also a pass-through mode – in case if you don’t need input voltage regulation. Remember: preventing a crisis is always cheaper than fixing it!

  • EN - Enable
  • GND - DC - (negative) terminal
  • IN - DC + (positive) terminal
  • OVP - Over Voltage Protection
  • RPP - Reverse Polarity Protection
  • OCP - Over Current Protection
  • OVP - Over Voltage Protection
  • PASS - Pass-through mode "+" (positive) terminal
  • GND - DC - (negative) terminal
  • OUT - Voltage converter output "+" (positive) terminal
Flow 1

EN - enable voltage down converter, High(9-60VDC) = on, Low(0-1.2VDC) = off EN can be used with car accessories of the vehicle ignition power switched on to enable a voltage converter; by default - a jumper enables a voltage-down converter.

Current limits shown on the case are for single output pass-through mode or regulated 5/12/23V mode, but not for both outputs simultaneously.

OUTPUT

PASS - pass-through mode - input voltage after protection circuit, EN input does not affect PASS output. OUT and PASS outputs can be used simultaneously. but the 3A input fuse limits the current, so the output power budget depends on the input voltage level.

Some ways to use the APA-1

INPUT FROM A CAR (12V), BUS(24V), TRACTOR OR OTHER VEHICLE

use 1

Using only PASS mode to connect a MiktoTik wAP or any other equipment.

use 2

Using the APA-1 5V output for another device.

use 3

Using STEP-DOWN 5V output for some equipment + the PASS option for the router + the EN with the automotive accessory electrical pin of the vehicle to enable some equipment

use 4

Using APA-1 in a boat with the GPeR IP67 Case
