The 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.
SRE Series (120W)
TFS Series (500W)
The TFS filter incorporates Eaton’s proven RIA12 surge and transient suppression circuitry, as used in many of our DC-DC converters. The filter is intended for use with the converters in our range which do not already have this protection built-in, thus enabling a system to be compliant with both BRB RIA12 and EN 50155. Rated at 500W (400W for the 24V model), the filter was originally designed for use in conjunction with our 500W PMR series, but is equally suitable for use with other converters at lower power levels. More than one converter can be fed from a single filter, provided the combined output power of all converters does not exceed the maximum rated power for the relevant model.
SQ Series (50W)
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.
USBR Series (25W)
The USBR converter is a very cost-effective USB charger designed specifically for use on rail vehicles. Housed in a rugged chassis mounting enclosure 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 provide 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.
VER Series (100W)
The 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.
T8 Rail Compliant LED Tube
T8 rail compliant LED tubes. These drop in replacement tubes are high reliability LED’s with built in drive electronics.
LPA also supply T5 rail compliant LED tubes, click here for more information.
D10R Series (10W)
The 10W D10R series is a range of low power converters, which incorporate full surge and transient protection to RIA 12 and EN50155. They are single output units with nominal inputs from 24Vdc up to 110Vdc. The D10R is available in encapsulated and open frame versions and can be supplied with pins for PCB mounting or input / output cables for bulkhead mounting.

ASR Snap Rectangular Connectors
A new concept in miniature connectors, the ASR connector is designed for performance, has a compact footprint and is easy to mate.
The ASR connector series features a simple self locking snap mechanism and with the ability to use in a blind mating situation. They connect and disconnect with two fingers!
It is lightweight, durable and environmentally sealed. The ASR connector is polarised in several aspects to prevent mis-mate, accepts standard mil spec contacts, RF contacts and can be supplied with PCB contacts.
Accessories including cable clamps and backshells are also available.
ARINC 404 Connectors
Arinc 404 rack and panel connectors are designed to meet or exceed the requirements of MIL-C-81659 and ARINC Specification 404.
The series is a multi-purpose connector used in aerospace, military, and computer periphery applications and others. These connectors are available in five shell styles with up to four insert cavities. Insert arrangements are available utilising a single type contact or a combination of standard and coaxial contacts.
Application specific designs including transient protection are available.
ARINC 600 Connectors
ARINC 600 Connectors are a recognised standard rack and panel connector for aircraft applications.
The ARINC 600 is the successor to the ARINC 404 for many of the new avionics designs. Compared to the ARINC 404, the ARINC 600 features lower mating force contacts, increased contact count and a front release, floating keying system.
The extensive product offering will meet the most demanding needs our of customers. At the design-in stage, we will work with you to select a connector from our standard product line or co-ordinate the design of an application specific connector.
The ARINC 600 rack and panel connectors are designed to meet all relevant ARINC 600 connector specifications.

Filter Connectors
Filter connectors have been used for many years as a cost effective and space saving solution to EMI issues in a wide range of aerospace, defence type applications.
A low pass filter connector incorporates capacitors and ferrite inductors generally within a standard connector body. Most filter types L, C, LC, Pi and T filters can be incorporated. In addition to this, more specific configurations using Diodes, Metal Oxide Veristors (MOV’s) and various Transient Voltage Suppression (TVS) devices to provide protection against EMP/ NEMP/ LEMP/ HEMP and ESD threats.
In conjunction with our partners we can offer an extensive range of standard and customised filter connectors including EMC and EMP protection for sensitive circuits used on a wide range of applications within military and civil aerospace, C4i systems, Vetronics, industrial and power distribution systems.
LPA can also supply filtered versions of application specific products as well as custom and integrated system solutions.
