Available from leading UK Power Conversion distributor PowerPax the Mornsun R3 series of DC/DC Converters features a completely new design structure ensuring high efficiency, excellent energy saving and competitive pricing. The range provides solutions to a number of common application issues and consists of more than 240 models in the power range 3 – 30W.
These converters feature single and dual O/P models in industry standard footprints with inputs of 9 – 18V DC, 18 – 36V DC & 36 – 72V DC for 2:1 input variants and 9 – 36V DC & 18 – 75V DC for 4:1 input variants, all models feature input under voltage protection. Single outputs include 3.3V, 5V, 9V, 12V, 15V and 24V, dual outputs include ±5V, ±12V, ±15V, ±24V.
This range provides a wide range of input to output isolation specifications with 1.5KV DC, 3KV DC and 6KV DC available in the series. This is one feature that makes this series suitable for a wide range of applications.
Industrial equipment generally operates at light loads with periods of high load requirement and as such the low load condition is outside of the standard operating parameters of many DC converters. In such cases a dummy load is often used but the result of this is an increase in temperature within the equipment through heat dissipation and unnecessary power usage. The R3 series significantly improves operation under such conditions through the use of variable frequency switching techniques to remove the requirement for a dummy load. The efficiency of this converter series exceeds 78% in the load range 5 – 30% and the no load power consumption is as low as 0.12W thereby reducing power consumption and preventing unwanted temperature rise.
These regulated converters have excellent stability characteristics with load regulation of ±0.5% and line regulation of ±0.2%. In addition outputs have low ripple and noise characteristics.
In many systems there is often an issue with the DC converter start-up time (typically >200mS) and in such cases measures need to be taken to ensure correct system start-up to ensure that the DC converter is in a stable state before system start-up proceeds. This issue is often compounded by the overshoot on the output as the DC converter starts and again measures are often taken to protect circuits from this, often using additional components. The R3 converters solve this issue by decreasing the start-up to 20mS without any overshoot on the output.
In situations where an abnormal shutdown of equipment occurs, commonly found in industrial systems, problems may occur. To overcome this condition the R3 series converters have a number of in-built protection features including input under-voltage, output over-voltage, over-current and self-recovering short circuit protection which enhance both safety and system reliability.
Compliance with EMC requirements is a must in today’s electronic systems and most DC converters will require an external capacitor to meet the required levels. This is not as issue for the R3 series converters which meet CISPR22/EN55022 Class A without the need for external components.
Environmentally this series of DC converters performs well with an operating temperature range of -40 to +85°C and a storage temperature range of -55 to +125°C.
In addition to the pcb mounting models there are also chassis and DIN rail mounting options available to enhance the capabilities of the series.
Power conversion components are the heart of any system and the reliability of such components is paramount to overall system reliability, especially in the harsh conditions that industrial systems need to operate in. All converters in this series have undergone full reliability testing throughout all phases from design to production and meet an MTBF 1000K hr’s (MIL-HDBK-217F@25°C). Reliability testing includes high temperature operation testing, low temperature operation testing, temperature cycle testing, thermal shock testing, and vibration testing. The reliability of these devices is enhanced by the fully automated manufacturing process which ensures high precision and repeatability.
This series of converters provide a step up in performance whilst remaining cost competitive with excellent lead times. Free samples are available from PowerPax by visiting www.mornsun.co.uk
These converters are suitable for a wide range of applications including; industrial instrumentation and control, medical instruments, electricity monitoring, telemetry, data transmission, telecommunications and robotics to name a few.
