Mean Well HRPG-450-15 Enclosed Power Supply

450 W enclosed supply with standby rail and remote sense

The Mean Well HRPG-450-15 is a 450 W enclosed switching power supply with a 15 V DC output at 30 A. The HRPG-450 series has a low-profile 41 mm case and, according to the datasheet, offers active PFC, a 5 V standby output, a DC OK signal, remote ON/OFF, remote sense, built-in fan control.

Input covers 85 to 264 VAC (120 to 370 VDC) with a PF above 0.95 at 230 VAC. Efficiency is 89% at 15 V and the series operates from -40 to +70 C. Overload is handled with constant-current limiting.

Technical specifications

Control functions built into the supply

The 5 V standby output stays alive when the main output is switched off through the remote ON/OFF input, so a controller can keep running while the 15 V rail is shut down. The DC OK signal reports that the main output is present, and remote sense wires compensate the voltage drop on long or heavy output cables. Fan control switches the fan on only above a load threshold or a temperature limit, which reduces fan noise at light load.

Selection and installation points

Typical loads for a 15 V rail include analogue and amplifier stages, instrumentation and communication equipment. The enclosed case has screw terminals, so install it inside an enclosure that provides touch protection. Allow free air flow for the fan, apply the derating curve in hot cabinets and check that the 70 A inrush at 230 VAC suits the upstream breaker. For an application that needs a 24 V rail the series also offers a 24 V model with 18.8 A. Connect the remote sense wires at the load terminals with a twisted pair, and check polarity before the first power-up.

How the HRPG-450-15 works

The HRPG-450-15 block diagram shows an EMI filter and rectifiers, an active PFC stage, a PWM power switching stage at about 70 kHz, and output rectifiers and filter that deliver the isolated 15 V rail. Overload is handled by constant-current limiting, and the protection circuits also cover short circuit, over-voltage and over-temperature. A built-in DC fan is controlled by load: it switches on at about 20±10% load, which reduces noise and fan wear at light load.

Check the datasheet wiring diagrams and notes before connecting any auxiliary signal or control function of the series.

Selection & Ordering Guide

The HRPG-450 series covers a wide range of output voltages:

• HRPG-450-3.3: 3.3 V, 90 A
• HRPG-450-5: 5 V, 90 A
• HRPG-450-7.5: 7.5 V, 60 A
• HRPG-450-12: 12 V, 37.5 A
• HRPG-450-15: 15 V, 30 A
• HRPG-450-24: 24 V, 18.8 A
• HRPG-450-36: 36 V, 12.5 A
• HRPG-450-48: 48 V, 9.5 A

Choose the HRPG-450-15 when a 15 V rail up to 30 A is needed, for example for analogue instrumentation, test equipment or 15 V drive electronics.

Installation & Maintenance

• Isolate and lock out the supply circuit before wiring; installation should be carried out by a qualified electrician.
• Use the conductor sizes, terminal data and protective earth connection shown in the official datasheet.
• Respect the mounting orientation and clearances given by Mean Well so that the cooling of the HRPG-450-15 works as designed.
• After commissioning, measure the output voltage at the load and trim it only within the documented adjustment range.
• During planned maintenance, check terminals for tightness and discolouration, remove dust, and confirm that the cabinet temperature stays inside the derating curve.

Typical Applications in Oman & the GCC

In Oman and the GCC the HRPG-450-15 is used in industrial control equipment, laboratory and test systems, instrumentation racks and machines that need a high-current 15 V supply in an enclosed format.

Wiring and commissioning notes for the HRPG-450-15

Before energising the HRPG-450-15, confirm that the AC input wiring matches the terminal markings and that the protective earth is connected. Size the output cables for the full 30 A load plus a margin, keep them short to limit voltage drop, and make sure the fan inlet and outlet are not blocked. After start-up, measure the voltage at the load terminals and trim it within the documented range if needed. Check the enclosure temperature at full load against the derating curve in the datasheet.
