¶ Wiring & Connections
¶ AC (Mains) Input
The LCP300-48 accepts a wide input range from 100-240VAC. There is no input voltage selection switch required.
The LCP300-48 features dual AC input terminals. Each terminal is capable of transferring currents of up to 12A. 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 LCP300-48 features four 48VDC output terminals.
A total combined output of 310W 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.
