Voltage Converters

Introduction:

The ENFORCER Voltage Converter is a low voltage step-down voltage converter. It converts low voltage AC or DC to one of three different regulated DC outputs. It is useful for CCTV DC cameras, access controls, as well as many other applications where low DC voltage is required.

Features:
• Selectable 5, 12, or 24 VDC output via jumper.	• Adjustable voltage output to compensate
• Built-in overload protection.	for voltage drop.
• Regulated and filtered output.	• Dual-color LED power output indicator:
• Output current protection:	– Red indicates 5/12 VDC output.
– 0.5 Amp for ST-LA105-TTQ	– Blue indicates 24 VDC output.
– 1.0 Amp for ST-LA110-TTQ	• Green power input LED indicator.

Installations:	Specifications:

1.Remove the cover by simultaneously pressing the 2 indented slots located on the side of the cover.

2.Set the desired output voltage to 5, 12, or 24 VDC. See table 3. The factory default output setting is 12 VDC.

3.Connect the output wires from the power supply to the power input terminal blocks. See specification chart for the power requirements. Turn on the power of the power supply.

4.Use table 2 to check the LED status for the input and output voltage.

5.To avoid potential damage, use a voltage meter to check if the voltage reading at the input and output terminal blocks is correct.

Observe correct polarity.

Note: 1. Use between 16 AWG and 26 AWG wire for the input and output terminal blocks.

2.Use the included SECO-LARMDC pigtail connector for easy installation.

6.Connect device to the power output terminal blocks.

7.If the output voltage is low, then turn the rotary knob clockwise to increase the voltage or counter- clockwise to decrease the voltage.

Note: If the output voltage set by the jumper is higher than the input voltage, then the output voltage reading will be the same as that of the input voltage.

8.Replace the plastic cover on the voltage converter and secure it in the desired location.
