BULK LOT 0F 47, Mean Well DR Series Step Shaped Single Output DIN Rail PSU. A range of step shaped DIN Rail power supplies from Mean Well. These power supply units are isolation Class II and have no load power consumption. The units are suitable for household appliances and building automation controls which are increasingly required in commercial and residential premises. Why use a DIN Rail Power Supply?The flexibility of DIN Rail mounting systems enables quicker installation time as all devices are able to simply snap onto the metal rails. Power supplies can be easily organised on DIN Rails within enclosed wall boxes or in areas where there is limited space. Similar devices can be mounted next to each other reducing the amount of cabling required. Most power supplies are convection cooled so no cooling fans are needed. DIN Rail AC/DC power supplies are widely used in many automation, instrumentation and industrial applications.
They are used to power a wide variety of DC operated devices including sensors, motors, actuators, solenoids and relays. DIN Rail size There are three common types of DIN Rails.Top Hat, G section and C section. Most have a depth of 7.5 mm or 15 mm. It is wise to check that your power supply is compatible with your DIN Rail. Protection Types It is important to choose a power supply that is protected against either short circuit, overload, over temperature or over voltage. Some power supplies also offer a hiccup mode which will allow the PSU to resume operation once the fault is cleared. Fixed or adjustable output voltage or current In test systems it is often convenient to have adjustable DC voltage however in other applications a fixed DC supply may be essential. Cabling and wiring The input/output lines to and from the power supply should be as short as possible with a large cross sectional area to help minimise noise and heat. Efficiency Choose a power supply that has an efficiency over 89% to minimise the amount of power dissipation, especially if the system relies on convection cooling. Standards If the power supply is to be used in the USA for controlling electric motors then it will need to comply with Standard UL508, the safety standard for industrial control equipment.
UL60950-1, TUV EN60950-1 approved, design refer to EN50178. AC or DC Input Voltage. AC or DC Output Voltage.
