The TEP 150WI Series was designed to support both railway and harsh industrial applications. With certification to EN 50155, the series meets a comprehensive list of criteria for environmental, shock, vibration, power supply, EMC, power surge, ESD and transient factors. The standard assumes that systems on rolling stock will need to operate 24/7 for 30 years, a minimum 250,000 hours, without failure. This means that train control systems must be designed to withstand the toughest environmental conditions. Compliance to the EN 50155 EMC requirements help ensure that systems do not interfere with each other when installed in close proximity. Since space is often tight in control panels, equipment can be mounted close together.
