Mean Well RSP-100-48 MEAN WELL Enclosed Power Supplies

Razz Middle East supplies MEAN WELL enclosed switch-mode power supplies in Saudi Arabia, sourced to order against the full model code. These are the metal-cased chassis units, including the LRS economy series and the higher-power RSP series, that mount inside a control cabinet and feed 24 V, 48 V and other DC rails. Each model is ordered by its complete code and delivered duty-paid, normally within three weeks.

About MEAN WELL Enclosed Power Supplies

An enclosed MEAN WELL code reads series, then wattage class, then nominal output. LRS-50-48 is the LRS series at the 50 W class with a 48 V output; LRS-350-4.2 is the same series at 350 W with a low-voltage 4.2 V output, which is why the third field must always be read rather than assumed. RSP-500-12, RSP-750-24 and RSP-1500-48 step through the RSP power-factor-corrected series. The practical differences between series matter more than the numbers. LRS is a slim, low-cost general-purpose chassis supply intended for cabinet 24 V control rails. RSP adds active power factor correction, higher power density and, on many models, remote sense, remote on-off and a fan-cooled or convection-cooled construction. Larger models in the range are built to work in parallel with active current sharing so several units can feed one bus. Every enclosed unit carries a published derating curve that sets how much output remains as ambient rises, and the higher-power fan-cooled models depend on unobstructed airflow. Output voltage is trimmable within a limited band on most models, which allows compensation for volt drop on a long DC run.

MEAN WELL Enclosed Power Supplies in Saudi Arabia

Enclosed supplies are the default 24 V source inside panels built in the Kingdom. Machine builders and panel shops in Riyadh, Dammam and Jeddah use LRS-class units for PLC, sensor and relay rails, and RSP-class units where the load is larger or where the incoming supply is monitored for power factor. Telecom, CCTV and access-control cabinets use 12 V and 48 V units. LED lighting and signage contractors use enclosed constant-voltage supplies indoors and in protected housings. Water and irrigation control cabinets, packaging lines, cold stores and building management panels all draw on the same range. Cabinet temperature is the deciding factor across most of the country: a panel on a rooftop, in a pump house or in an unconditioned plant room in Jubail or Yanbu runs far above European design ambient, so units are usually chosen with real headroom against the published derating curve rather than at nameplate wattage. Input is normally 220-240 V single phase at 60 Hz, and imported equipment must satisfy the applicable SASO conformity requirements.

Ordering and lead time

Quote the series, the wattage class and the output voltage together, and include any trailing letter. Give the continuous load rather than the peak, and add the inrush of anything the rail feeds, such as contactor coils or a group of solenoid valves, because a supply sized to the steady-state figure will drop out on switch-on. State the ambient the cabinet actually reaches, not the room temperature, and say whether the panel is ventilated. If several units will feed one bus, say so, since parallel operation requires a model that supports current sharing. Confirm whether you need remote sense, remote on-off, a DC-OK signal or conformal coating, as these separate otherwise similar model codes. Units are sourced to order and delivered duty-paid, with a normal lead time of three weeks; high-wattage and less common output voltages can take longer.
