¶ Wiring & Connections
¶ AC (Mains) Input
The LCP300-24D5 accepts a wide input range from 100-240VAC. There is no input voltage selection switch required.
The LCP300-24D5 features dual AC input terminals. Each terminal is capable of transferring currents of up to 12A. In theory this allows for additional AC loads to be daisy chained through the power supply, greatly simplifying wiring.
The input connectors use M3 barrier terminals. SV2-3 or equivalent fork spade terminals are recommended for wiring.
¶ Output Terminals
The LCP300-24D5 features three 24VDC output terminals and a single 5VDC output. The 5V output is generated using an internal step-down buck converter from the 24V rail.
A total combined output of 300W is possible. However, at maximum output, the power supply can become significantly hot, and external airflow directed at the casing is recommended in this situation.
The output connectors use standard screw terminals. While bare stripped wires can be used, it is highly recommended to use ferrules. Ferrules up to size VE1508 can be used.
