SynQor® Releases an Using Current Sense Resistors to Improve Efficiency

What are current sense resistors?

Current sense resistors, or shunt resistors, are devices used to gauge the flow of current. They detect and convert current to a measured output voltage. Current sense resistors are generally low-value, high-power resistors. They are designed for low resistance to minimise power consumption and to eliminate the risk of short circuits which are likely to damage other components.

The proportional relationship between voltage and current, according to Ohm’s Law enables a sensor circuit to measure the amperes delivered to a load in real-time. This is a cost-effective and straightforward method of current flow measurement and is used to mitigate the effects of short-circuits or overloads and to maximise the efficiency of electrical systems. 

At TT Electronics, we offer a full spectrum of resistor technologies and a broad standard product range, in addition to providing custom engineering solutions. We dedicate ourselves to staying on top of the competitive landscape engineers are faced with today when designing a current flow measuring system.

SynQor® Releases an Advanced Military-Grade DC Output, Shallow Rack Power Conditioner (MPC-1250)

SynQor, Inc., a leading supplier of power conversion solutions, announces the newest member of its Military Field-Grade Power Conditioners.  The Shallow Rack Mount MPC is packaged into a 17.00”W x 14.80”D x 1.73”H, 22 lb. enclosure designed for the harshest environments.  The MPC-1250 is a true on-line double conversion, isolated, fully regulated 1250 W DC output power supply. The unit has a universal, single phase AC input which accepts input voltages between 80 Vac – 265 Vac (47-65 Hz), with an optional wide frequency range (47-800 Hz).  The unit can also be powered from an alternate DC input source between (22 Vdc – 33 Vdc). Additional built-in features include soft start, fault recognition and recovery conditions for overload, input under voltage and over voltage and temperature abnormalities.
Multiple units can be parallel to deliver a higher power. An inter-unit communication link allows multiple units to behave as a single system while delivering higher combined power or providing a fully M+N redundant system. 
The MPC system includes features that allow remote tracking of the unit’s systems via the industry standard SNMP or an intuitive GUI driven web interface. The users can track various operational parameters like the output and input parameters, temperature, fan speed and much more.  Users can also set up SNMP traps and configure email alerts so that they can be notified of events that could put the operation of a remote site in jeopardy.
The Shallow Rack MPCs have been designed to meet several of the most demanding electrical military standards, including MIL-STD-704F, 1399-300B and 461F.  The MPC not only has electrically superior characteristics to many power supplies of its kind, but it has been designed to comply with the harshest of environmental conditions as required by MIL-STD-810G in a compact and ultra-light weight package.
SynQor’s design and manufacturing teams deliver reliable products that are the best in market in terms of their electrical functionality, mechanical specifications and durability.


  • 1250 W isolated full power DC output (24 Vdc and 28 Vdc)

2020: The Year of the Tact Switch

2020 brought with it many trials and tribulations, but it hasn’t been all bad, has it? We like to look at the positives though too. A new wave of innovations and ideas also rode the wave of change that this challenging year brought. E-Switch released 3 new Tact Switches, each one with a specific function to assist our valued end-users. 

Towards the start of the year, as the national lockdown was beginning, the TL6340 made its first appearance. The tiny right angle surface-mount Tact Switch left a big imprint on the industry. Perfect for small, limited space applications that still require quality, durable mechanics; with an IP67 rating and a mechanical life of 200,000 cycles, the TL6340 is up to all most all tasks you throw its way!

As Spring came to a close and state-wide quarantine still firmly in place, a new Tact Switch blossomed into the world, the TL9320. Another hardy switch with a moisture protection rating of IP67 giving complete protection against temporary water submersion; this combined with its 500,000 cycle life-expectancy makes the TL9320 well suited to a variety of applications in multiple demanding markets.

That brings us finally to September with the release of our most recent Tact Switch, the TL3145. With 3 actuation forces to choose from and 2 actuator heights available, this switch screams versatility. Not only that, but the TL3145 continues the theme for a rugged, built to last Tact Switch series. With an operating temperature of -40°C to 85°C and an outstanding 3,000,000 cycles using the 180gf option!
