D10R Series (10W)

The 15W MBR series consists of low power encapsulated converters which incorporate full surge and transient protection to RIA12 and EN50155. They are available in single, dual, and triple output versions, with nominal inputs from 24V up to 110V. Normally supplied with pins for PCB mounting, they are also available with flying leads for bulkhead mounting.

The 25W MBRH is an enhanced version of the well established Martek Power 15W MBR series and is recomended for new designs. The MBRH offers all the same electrical features as the MBR, and in the same enclosure, but at an increased output power rating of 25 Watts. One of the main benefits of both the MBR and MBRH over similar products is that they incorporate all of the components necessary for full EMC compliance and EN50155 class S2 interruptions (10ms hold-up time). It is not necessary for any additional filtering or capacitors to be added by the end user. Intended for rail applications, these encapsulated modules are fully compliant with both the latest European norms and the older BRB RIA standards.

The 25W USBR converter is a very cost-effective USB charger designed specifically for use on rail vehicles. Housed in a rugged chassis mounting enclosure and rated to IP40, IP56, or IP65. The converter’s small size makes it ideal for mounting almost anywhere in the passenger compartment such as within passenger seat frames. Models are available for direct connection to the vehicle battery (dc input), or an auxiliary 110/230Vac supply, and provides two independent 5V outputs, each rated at 2A. The range is fully compliant with the latest international railway standards including shock and vibration, EMC and fire protection.

Originally designed for on-board passenger information systems, the 35 -50W JL series is now available in a wide variety of input and output configurations. Capable of providing 35W, 50W or 60W of continuous power at ambient temperatures of up to +75°C, the low component count makes the JL series a highly reliable and cost-effective solution. For applications where the converter will be housed within an enclosure, the open frame version offers a further cost saving. The JL and JLH series have recently expanded to include alternative size footprints, connectors and functional features.

The 50W SQ Series converter has a very low profile, open frame construction and is intended for installation within the host equipment. The topology employed offers very high efficiency with outputs as low as 3.3V and is therefore ideal for driving LEDs in applications such as low voltage lighting and Passenger Information Systems. Compliance with UK RIA standards, as well as current national and international railway norms, makes the SQ series equally suited to both new build and refurbishment applications.

The 55W ABR series is designed specifically for use in rail applications, and is equally suited to both on-board and trackside applications. Housed in a rugged 3U Euro cassette, the ABR series can be installed in a rack or chassis mounted. The range is fully compliant with international railway standards and norms.

The 55W DR series is a well-established product range designed specifically for use on railway rolling stock. Units are available in single, dual and triple output versions with input ranges to cover those typically found in rail applications. Housed in a rugged 3U Euro cassette, the DR series is a suitable for both rack and bulkhead mounting. The range is fully compliant with the current national and international railway standards and norms.

The PMEL series is the low power model in a new range of highly cost effective, single output converters for chassis mounting. The range is fully compliant with the latest European standards for railway equipment, including EMC and fire and smoke.

The 100W CPCIR series is a compact PCI converter which is fully compliant with international railway standards. Designed specifically to meet the demanding requirements of EN50155, the CPCIR series is ideally suited to on-board computer applications.

The 100W CPCIR series is a compact PCI converter which is fully compliant with international railway standards. Designed specifically to meet the demanding requirements of EN50155, the CPCIR series is ideally suited to on-board computer applications.

The 100W VER series is a range of cost effective, medium power, single output converters. Featuring a very small footprint, the standard version complies fully with the latest rail specifications and norms for protection and EMC. For applications requiring compliance with class S2 supply interruptions (10ms hold-up time), an enhanced version is available which also adds active inrush current limiting and output health indication.

The 120W SRE series is a very low profile converter designed specifically for use on railway rolling stock. Rated at 120W, units are available in single or dual output configurations with input ranges to cover those typically found in rail applications. The unit is suitable for either rack or bulkhead mounting. The range is fully compliant with the current national and international railway standards and norms.

The 140W EBR series is a single output unit, which has been widely used for supplying the power to train radios. The converter meets RIA rail standards and many thousands are now in service. The standard unit has been adapted for several other rail applications, with alternative input and output voltage combinations.

The 150W ER series is a well-established product range designed specifically for use on railway rolling stock. Units are available in single and dual output versions with input ranges to cover all typically found in rail applications. Housed in a rugged 3U Eurocassette, the ER series is suitable for both rack and bulkhead mounting.

The 150W ERL series is based upon the well-established Martek Power ER series. The ERL offers a lower cost alternative for customers that do not require any of the extensive electrical options which are available with the ER. In all other respects it is identical to the original ER Series, including mechanical formats and pin assignments. Housed in a rugged 3U Eurocassette, the ERL series is suitable for both rack and bulkhead mounting and is available with either a heatsink or cold wall mounting plate. The range is fully compliant with the current national and international railway standards and norms.

The 150W PMEM series is the intermediate power model in a new range of highly cost effective, single output converters for chassis mounting. The range is fully compliant with the latest European standards for railway equipment, including EMC, fire and smoke.

The 200W XER series is a range of very cost effective medium power, single output converters. The range is compliant with the latest European standards for railway equipment, including EMC, fire and smoke.

The 200 – 400W NS series is a range of medium and high power single output converters that comply fully with both the traditional and latest rail specifications and norms for protection and EMC. The rugged construction and mounting arrangement ensures compliance with vibration and shock requirements.

The 300W ATG series is a range of cost-effective, medium power single output converters that comply fully with the latest rail specifications and norms for protection and EMC. Although simple in construction, the mounting arrangement ensures compliance with the vibration and shock requirements of EN50155.
