description
The VHK200W series of rugged DC-DC converters are designed for high reliability applications, featuring integral heat sink, over-temperature protection, over-current protection and input transient voltage protection. With an external input fuse, the converter can protect accidental input polarity reversal. The wide 4:1 input range (10-36V or 18- 75V) is very useful to stabilize an input source like batteries in various discharging and charging conditions. Additionally, high efficiency, fast response, tight regulations, remote sense and remote On/Off control make these converters very useful in many industrial and communications applications.

DESCRIPTION: chassis mount dc-dc converter 4 of 10 PART NUMBER: VHK200W APPLICATION NOTES 1. OUTPUT DE-RATING The operating ambient temperature range for VHK200W is -40 ~ +100°C, with the actual output power subject to the following de-rating curves at free-air convection and at forced air conditions. To ensure long-term reliability, it is important to ensu re proper cooling at the worst operating conditions. FIGURE 1a.

FIGURE 1b. OUTPUT DERATING (48 V) 2. INPUT VOLTAGE RANGE It is important to ensure the input voltage measured at the converter input pins is within the range for that converter. Make sure wire losses and voltage ripples are accounted for. One possible problem is driving the converter with a linear unregulated power su pply. For example, if the average voltage measured by a DMM is 9V, with a voltage ripple of 3Vpp, the actual input can swing from 7.5 V to 10.5V. This will be outside the specified input range of 10-36V and the converter may not function properly. On the other end, make sure the actual input voltage does not exceed the highest voltage of 36V or 75V. 3. LEAD WIRES Make sure the input and output wires are of adequate AWG size to minimize voltage drop, and ensure the voltage across the input terminals is above the converter's rated minimum voltage at all times. It is recommended to have the wire pairs twisted, respe ctively for the input pair and the output pair, so as to minimize noise pickup. page date DESCRIPTION: chassis mount dc-dc converter 5 of 10 PART NUMBER: VHK200W VHK200W-Q48 Power Derating Curves @ Nominal Input 20% 40% 60% 80% 100% 120% - 4 0 1 52 02 53 03 54 04 55 05 56 06 57 07 58 08 5 Ambient Temperature - degrees C Relative Output Power - % of nominal output Natural Convection 0.5 m/S (100LFM) 1.0 m/S (200LFM) 1.5 m/S (300LFM) 2.0 m/S (400LFM) 2.5 m/S (500LFM) 3.0 m/S (600LFM) 3.5 m/S (700LFM)
