Introduction

  • The Olycom IM-DAC220/DC48V1.6A is a 75W slim-profile industrial DIN-rail power supply purpose-built for deployments where 48V DC is needed but available panel space is not. 
  • At just 32mm wide, it is the most space-efficient entry point in the Olycom 48V DIN-rail PSU lineup — delivering a clean, stable DC 48V / 1.6A output for single PoE switch feeds, individual communication modules, and low-to-medium power automation loads where a 120W or 240W supply would be oversized and wasteful.
  • Behind that slim profile is a specification sheet that punches well above the 75W class: a wide-range AC/DC input accepting 90–264VAC or 120–370VDC through a single shared terminal, a power factor up to 0.98 at 115VAC, 4000VAC input-to-output isolation, comprehensive protection across short-circuit, over-current, over-voltage, and over-temperature events — all with auto-recovery so a fault condition clears itself without a site visit. 
  • An MTBF exceeding 300,000 hours (MIL-HDBK-217F @ 25°C) and a -30°C to +70°C operating range round out a platform engineered for the long, unattended operational lifetimes that industrial and infrastructure deployments demand.

Key Features

  • Ultra-Slim 32mm DIN-Rail Profile — The narrowest 48V supply in the Olycom PSU series; mounts on standard TS35/7.5 or TS35/15 DIN rail; aluminum and SGCC steel enclosure; occupies minimal panel space in dense automation cabinets and compact field enclosures
  • Universal Wide-Range AC/DC Input — Accepts 90–264VAC or 120–370VDC through a single shared input terminal; covers global grid voltages and DC bus sources without rewiring or adapters; input frequency 47–63Hz; input current ≤2A @ 115VAC / ≤1A @ 230VAC
  • High Power Factor Correction — PF up to 0.98 at 115VAC / 0.94 at 230VAC; reduces reactive power draw and harmonic current injection; EN61000-3-2 Class A harmonic emission compliance
  • Stable 48V / 1.6A Output, 76.8W Total — Voltage accuracy ±1%; line regulation ±0.5%; load regulation ±1%; ripple and noise ≤150mVp-p; temperature coefficient ±0.03%/°C — output stability that PoE switches and sensitive communication equipment require
  • Extended Hold-Up Time — 12ms @ 115VAC / 60ms @ 230VAC; maintains output during brief input interruptions without resetting connected equipment — critical for communication and control systems where a momentary mains dip cannot trigger a system restart
  • 4000VAC Input-to-Output Isolation — Exceeds standard industrial isolation requirements; protects connected equipment and personnel from high-voltage input faults; Input–Earth 2000VAC, Output–Earth 500VAC
  • Comprehensive Auto-Recovery Protection Suite:
  • Short-circuit protection — hiccup mode, self-recovering
  • Over-current protection — triggers at 105–150% rated output current, auto-recovers
  • Over-voltage protection — clamps at ≤60V output
  • Over-temperature shutdown — auto-recovers when thermal condition clears
  • MTBF ≥ 300,000 Hours — MIL-HDBK-217F @ 25°C; one of the highest reliability ratings in the 75W DIN-rail class
  • -30°C to +70°C Operating Range — Full performance from cold industrial spaces and unheated outdoor cabinets through high-ambient enclosures; derating applies above +45°C; humidity 20–95% RH non-condensing
  • EMC Immunity: IEC/EN 61000-4-2/3/4/5/6/11 — ESD ±8KV air, surge ±4KV line-to-ground; EN55032 Class B emission; full industrial electromagnetic immunity suite
  • Fanless Natural Convection Cooling — No moving parts; zero maintenance; silent operation; no filter cleaning; no fan replacement over the product’s operational lifetime
  • Multi-Standard Safety Certified — CE, FCC, IS13252 (Part 1), EN62368-1, UL61010-1 Class I safety design

Applications

  • Single PoE Switch or Injector Power Feed — The 75W output precisely matches the power requirement of compact PoE switches in the 60–80W budget range — including Olycom’s own IM-WP054GE and similar 4-port PoE platforms — where a larger 120W or 240W PSU would supply twice the power the switch can actually use. The slim 32mm form factor allows the PSU and switch to share a short DIN-rail segment inside a compact field enclosure without space compromise
  • Industrial Communication Module Power — Provides a clean, well-isolated 48V rail for fiber media converters, serial device servers, industrial routers, and protocol gateways in automation cabinets where the 4000VAC input-to-output isolation protects sensitive communication hardware from high-voltage transients on the mains supply side
  • Single IP Camera or Access Point Power Supply — In installations where a PoE injector or a single-port PoE power source is preferred over a multi-port switch — a single outdoor camera at a remote post, a single AP in a ceiling void — the IM-DAC220/DC48V1.6A provides the 48V DC source that a PoE injector draws from, with the full protection and isolation suite that a bare DC adapter cannot offer
  • Railway & Transportation Control Cabinets — The wide temperature range, EN61000-4 immunity suite, and 300,000+ hour MTBF qualify this PSU for trackside signaling panels, station control cabinets, and vehicle-mounted control systems where long unattended service life and immunity to traction power interference are mandatory requirements. The 60ms hold-up time at 230VAC covers the brief mains interruptions common in railway power environments
  • Smart Traffic & Roadside Infrastructure — Powers communication and control modules inside roadside cabinets at traffic signals, highway monitoring points, and variable message sign controllers, where the wide AC/DC input range handles both grid-tied and backup battery sources from the same terminal, and auto-recovery protection ensures the supply restores itself after surge events without a field technician visit
  • Renewable Energy Control Systems — In solar and wind energy installations, control system electronics — monitoring PLCs, data loggers, communication gateways — are often powered from DC bus sources at varying voltages. The 120–370VDC input range accommodates high-voltage DC bus sources directly, eliminating an intermediate DC-DC conversion stage and the efficiency loss and additional failure point it introduces
  • Distributed Building Automation Nodes — Powers 48V control devices — door controllers, BMS field panels, intercom systems, environmental sensors — at individual floor or zone distribution boards in commercial buildings, where the slim 32mm profile fits alongside circuit breakers and other DIN-rail devices in standard distribution enclosures without requiring a dedicated PSU slot
  • Substations & Utility Grid Edge Equipment — The 4000VAC isolation barrier and comprehensive IEC 61000-4 immunity make this PSU suitable for protection relay auxiliary power, metering panel supplies, and RTU power feeds in electrical substations where the electromagnetic environment from high-voltage switching operations places exceptional demands on power supply noise immunity
