SECO-LARM USA EVT-PB1-H05Q Voltage Booster Efficiency Rate, Troubleshooting, SECO-LARMU.S.A., Inc

ENFORCER Video, Power and Data Balun with Voltage Booster

Voltage Booster Efficiency Rate:

The EVT-PB1-H05Q has a power efficiency rating of 85%. Under typical conditions, the booster will provide sufficient power to compensate for long cable runs. The following formulas can be used to determine if enough power is present at the power input of the voltage booster:

1.Calculate the amount of power measured in Watts: Voltage x Current = Power

2.For example, if the voltage is 12VDC, and the current is 750mA: 12VDC x .75 = 9 Watts

3.Then calculate the amount of power using the voltage booster with the following formula: Power Input x Efficiency Rate = Power Output.

4.Using the 9 Watts in the previous example, calculate power input of the booster:

9 Watts x .85 = 7.65 Watts

5.After the power has been calculated, the output current is calculated from the following formula: Power / Voltage = Current

6.Using the example of 9 watts present at the power input, and 7.65 Watts at the power output:

7.65Watts / 12VDC = 640mA of available current

Use Table 3 to determine if additional pairs of Cat5 cable will be needed to transmit power.

Troubleshooting:

Output voltage is low/high	Check voltage jumper settings
	Check output voltage adjustment.
	Check input voltage to make sure it meets the input
	requirements
Green input LED not on	Check input power connections with multimeter to verify
	correct input voltage
Blue/red output LED not on	Check to see if the load exceeds the maximum limit
	Temporarily disconnect power input and output wires for 30
	seconds before connecting
