Introduction
An open frame (PCB) type switching power supply is a power supply designed to be integrated or installed into a
system enclosure. Mean Well’s open frame (PCB) type power supplies include on board, general PCB, green PCB,
and medical PCB types.
Installation
( )1Before commencing any installation or maintenance work, please disconnect your system from the
utility. Ensure that it cannot be re-connected inadvertently!
( )2At least 5mm insulation distance on the bottom of the unit should be kept and a Mylar film should be
added between the unit and the system. In addition, keep enough insulation distance, 10mm for
general type/15mm for medical type, around the unit.
( )3Power supplies greater than 120W may require a forced air/fan for cooling. Please refer to
specifications to receive a minimum air intensity and air-flow direction.
( )4Allow good ventilation for the unit in use to prevent it from overheating. Also, a 10-15 cm clearance
must be kept when the adjacent device is a heat source.
( )5Mounting orientations other than standard orientation or operate under high ambient temperature
may increase the internal component temperature and will require a de-rating in output current.
Please refer to the specification sheets to receive the optimum mounting position and information
about the de-rating curve.
( )6Recommended wires are shown as below.
AWG 18 16 14 12 10 8
Rated Current of
Equipment (Amp) 6A 6-10A 10-16A 16-25A 25-32A 32-40A
Cross-section of
Lead(mm2 ) 0.75 1.00 1.5 2.5 4 6
Note:Current each wire carries should be de-rated to 80% of the current
suggested above when using 5 or more wires connected to the unit.
( )7 For other information about the products, please refer to www.meanwell.com for details.
Warning / Caution !!
( )1Risk of electrical shock and energy hazard. All failure should be examined by a qualified technician.
Please do not try to fix the power supply by yourself!
( )2Please do not install power supplies in places with high moisture or near the water.
( )3Please do not install power supplies in places with high ambient temperature or near fire source.
Please refer to the specifications about the maximum ambient temperature limitations.
( )4Output current and output wattage must not exceed the rated values on specifications.
( )5The ground (FG) must be connected to earth ground.
( )6All MW’s PSUs are designed in accordance with EMC regulations and the related test reports are
available by request. Since they are belong to component power supplies and will be installed inside
system enclosure, when they are integrated into a system, the EMC characteristics of the end
system must be re-verified again.
