Power modules seal out the environment
Environmentally sealed power modules are ideal for telecomms basestations, towers and shelters, offshore platforms, chemical plants, mobile vehicles and other unsavoury applications.
When traditional forced air-cooled power modules are exposed to outdoor, industrial or other harsh environments, they ingest various contaminants including dust, sand, humidity, corrosive atmospheres, salt, fog, vermin and other debris These contaminants cause untimely failures due to shorts, corrosion and physical damage

Programmable electronic loads join the net
Transistor Devices' Dynaload Division has added Ethernet communication capabilities to its popular line of programmable electronic loads.
Power module is made for 1U systems
The Signature 1000W, 1U power module provides -54V DC for rectifier applications and +48V DC for front end architectures.
Fan filters often add to the problem as they become clogged, causing over temperature failures as cooling air is choked off.
The solution is a mechanical and electrical, ruggedised design with convection cooling that environmentally seals the equipment and protects the components.
TDI is introducing a complete series of environmentally sealed power modules (ESPMs).
The first modules to be released in this series are the highly efficient and ruggedised 1000 and 2700W units.
These modules are designed to withstand and operate reliably in harsh environments and critical applications.
The ESPM series is also electrically hardened to survive severe AC input transients.
Performance features include high efficiency operation, wide AC input ranges, sinusoidal power factor correction, remote control and monitoring, N+1 redundant parallel operation, EMI conformance and closely regulated and conditioned output.
The internal electronics are encased within the sealed aluminium chassis that provides environmental protection from the elements.
The 1000W module is encapsulated with a thermally conductive, flexible silicon elastomer, whereas the 2700W modules are filled with thermally conductive oil.
Both technologies efficiently conduct heat from the components to the finned chassis and in turn to the outside cooling air.
The ESPM series is ideally suited for telecommunications basestations, towers and shelters, offshore platforms, chemical plants, industrial processing and control, mobile trucks and vehicles, and other unsavoury applications.
ESPMs are NEMA rated for watertight, submersible, dusttight, corrosion resistant, steel resistant and hazardous locations.
They have an extended operational temperature range of -30 to +55C after a 30 minute warm up, which can be extended to +70C with power derating.
Their audible noise is undetectable.
Connection options include tethered cables, terminal blocks or weather tight connectors.
ESPM modules are available rated at 1000 and 2700W.
Other modules will be released later this year.
