PMT-12V350W1AR Power supply Delta Electronics PMT 350 W 12 V

PMT-12V350W1AR is a Delta PMT switching power supply (enclosed design) rated at 350 W with a 12 V DC output and up to 29.17 A. It has a single regulated output and a universal single-phase 85–264 V AC input, so one unit runs from both 110 V and 230 V mains without any switching. The IP20 rating suits installation inside an enclosed cabinet, box or instrument housing; the unit mounts directly into equipment where there is no room for a DIN rail.

Typical applications:

• 12 V LED lighting and backlighting
• relays, sensors and limit switches in automation
• cooling fans, audible and visual alarm devices
• high-power units and multi-channel loads inside equipment

Delta PMT — compact panel-mount power supplies for built-in equipment

PMT is Delta Electronics' line of switching power supplies for panel and built-in mounting. These are enclosed and panel-type AC/DC converters installed inside a machine housing, an instrument cabinet or a module — wherever there is no room for a DIN rail but a stable DC source is still required. The range covers power ratings from 35 to 350 W and four standard output voltages: 5, 12, 24 and 48 V DC. Every model accepts a single-phase universal input of 85–264 V AC, so one unit runs from both 110 V and 230 V mains without any switching — convenient for export machinery and unstable grids.

By form factor, PMT supplies are compact single-output sources: each model delivers one fixed voltage. Depending on the model it comes as a panel or enclosed version mounted directly into the equipment. The enclosure rating is IP20, meaning the unit is designed for installation inside a closed cabinet, box or instrument housing that already protects it from dust and splashes.

PMT model range by voltage

• 5 V: a 50 W model rated up to 10 A — for powering logic, microcontroller boards and TTL circuits.
• 12 V: the widest branch of the series — 35, 50, 75, 100, 150, 200 and 350 W, with output current from 2.92 to 29.17 A. For LED lighting, relays, sensors and 12 V automation devices.
• 24 V: 50, 75, 100, 150 and 350 W, current from 2.08 to 14.58 A — the most demanded rating in industrial automation.
• 48 V: 75, 100 and 350 W, current from 1.56 to 7.29 A — for telecom equipment, servo drives and systems with a 48 V supply bus.

Typical applications

Thanks to a single regulated output and universal input, PMT is used where the power supply is built directly into a product or assembly:

• powering PLCs, I/O modules and controllers (24 V);
• sensors, limit switches, relays and automation starters;
• LED lighting and indication (12 and 24 V);
• telecom and networking equipment running on 48 V;
• control logic and boards inside machines, instruments and operator panels (5 and 12 V);
• OEM equipment and modules where the power source is integrated into the product housing.

How PMT differs from other Delta series

Delta splits its power supplies by mounting method. The DRL, DRM and DRP series are designed for DIN-rail mounting inside an electrical cabinet — the classic industrial format for distribution boards. The panel/enclosed family (PMC, PMT, PMU) is meant for building into equipment. Within that family, PMT is the compact panel and enclosed version with a single output and 5/12/24/48 V ratings, aimed at integration inside machines and instruments rather than mounting in a distribution board.

A practical note: if you need a DIN-rail unit for an automation cabinet, look at the Delta DR series; if the power source has to be hidden inside an equipment housing or an OEM module, PMT is the best fit. Before ordering, verify the exact model code (voltage, power and version — panel or enclosed), because within a single power rating PMT exists in several mechanical variants.
