The product range offers a nominal output voltage of 24V, a wide temperature range from -10°C to +70°C and a highly dependable minimum holdup time. The state-of- the-art design is made to withstand harsh industrial environments. What makes the product stands out from the crowd is its lightweight full aluminum body design which can withstand shock and vibration according to IEC60068-2. Delta’s Panel Mount Power Supply also offers overvoltage and overload protection. Using a wide input voltage range design, it is compatible worldwide. The input also includes DC operating voltage from 100-375Vdc. Best of all, this excellent design and quality does not come with a big price tag.

Panel Mount Power Supply 24V 75W 1Phase Over Load Protection Over Voltage Protection The Power Supply is provided with an overload The Power Supply is protected by Over voltage in the protection (OLP/OCP) function which protects the power event that power supply feedback circuit fails the output supply from possible damage by over current. voltage will not be > 32V, +10% under any Line/Load Additionally power supply also has over temperature protection (OTP) in case the over load condition persists and operating ambient conditions.

The unique feature about this over voltage protection (OVP) is that power for a longer duration and is below the overload trigger supply doesn’t shut down but goes Hicc-up mode (Auto point but > 100% load. Typically the over load current recovery) which is 32V, +/-10%. The power supply (I OL ) is > I SURGE (120%) output voltage will start drooping output voltage will recover back to 24Vdc once the fault down when the power supply reaches max power limit and will run into bouncing mode when the output reaches condition is removed. Short Circuit Protection UVLO (under voltage point).

The output voltage will recover automatically when the overload condition is The Power Supply also has a short circuit protection removed. Over Temperature Protection which is in line with the overload protection and activates whenever there is a short across the output voltage, output goes in bouncing mode and remains Additionally power supply also has over until the fault is removed. temperature protection (OTP) as mentioned above this OTP comes into picture when the over load condition persists for a longer duration and the output current level is below the overload trigger point but > 100% load.

Also in the event of a higher ambient operating condition with 100% load the power supply will run into OTP when the ambient temperature is > 55°C. The protection is self recoverable when activated output voltage bounces until the operating ambient temperature of the power supply is reduced or the power supply is used within its power derating curve. www.DeltaPSU.com 4 PROTECTION 32V +10%/-10%, SELV output, Hicc-up Mode, Non-Latching Over Voltage Protection (Auto recovery). > 120% of rated load current, Hicc-up Mode, Non-Latching Over Load, Over Current Protection (Auto recovery).

Panel Mount Power Supply 24V 75W 1Phase Derating Curve Note 1. Do not use the power supply in areas outside the shaded portion as shown in the above graph, internal parts may occasionally deteriorate or be damaged. 2. For the power derating refer above graph ambient temperature > 50°C, the output capacity has to be reduced by 2.5% per Kelvin increase in temperature. If the output capacity is not reduced when Amb > 50°C device will run into thermal protection by switching off i.e. device will go in bouncing mode and will recover when Amb is lowered or load is reduced as far as necessary to keep device in working condition. 3.

If the power supply has to be mounted in any other direction please contact your service provider. 4. In order for the device to function in the manner intended, it is also necessary to observe lateral spacing of 20mm. to other modules. 5. Depending on the ambient temperature and load of the device, the temperature of the housing can become very high! www.DeltaPSU.com 5
