PSU-1200

The PSU-1200S is a switching power supply for Pantron high power opto sensors, ISM-series devices, and compact opto sensors in 115 V AC and 230 V AC environments. It accepts 95 to 265 V AC input, provides selectable 15 V DC or 24 V DC output up to 10 W, and adds relay output, NPN/PNP input compatibility, selectable light/dark operation, and adjustable switching delays on the front panel.

Key Features

  • Wide operating voltage range from 95 to 265 V AC for both 115 V AC and 230 V AC installations.
  • Selectable stabilized output voltage of 15 V DC or 24 V DC with up to 10 W output power.
  • Relay output with NPN / PNP control input support.
  • Selectable light or dark switching behavior via front DIP switch.
  • Adjustable switching-on and switching-off delay from 0 to 10 seconds.
  • Integrated overload, short-circuit, and overtemperature protection with DIN rail mounting to EN 60715.

Product Overview

The PSU-1200S combines a compact DIN rail switching power supply with signal handling functions that simplify panel wiring for Pantron sensing systems. It uses energy-saving switching supply technology with efficiency above 74% and a safety transformer for galvanic separation from the operating voltage.

The front panel provides access to the output voltage selection, relay behavior, and switching delay settings, while status indicators show adjusted output voltage, input and output status, and overload condition. This makes the unit useful where a single DIN rail device needs to power a sensor system and also provide delayed relay switching logic.

Its housing follows DIN 43880 dimensions for straightforward integration into industrial control cabinets.

This model is a good fit when the application needs both regulated DC power and configurable relay switching functions in one DIN rail package.

Installation Notes

  • Designed for DIN rail cabinet installation in industrial control environments.
  • No external fuse is required on the AC input side.
  • Inrush current limiting helps prevent overload when switching on.
  • Front-panel indicators display output voltage selection, I/O status, and overload condition.
  • Relay timing and light/dark logic can be tuned directly on the front panel.

Typical Use Cases

Application Why PSU-1200 fits
ISM-series control cabinets Supplies regulated 15/24 V DC power and provides relay switching for amplifier-based sensing systems.
Compact opto sensor panels Supports Pantron compact sensor hardware with selectable logic input behavior and protected output power.
Retrofit machine enclosures Wide AC input range and DIN housing simplify upgrades in mixed-voltage cabinets.
Applications needing timing control Adjustable 0 to 10 s switching delay helps manage controlled on/off behavior without adding a separate timing relay.
