EDAC Power EP190A Series - 900 W Continuous, 1500 W Peak, 29 mm Low-Profile Enclosed AC/DC Power Supply
High Power in a 29 mm Profile - With Peak Output Headroom for Demanding Industrial Loads
Industrial automation systems, semiconductor equipment, and robotics platforms share a recurring power design challenge. Equipment startup and sudden load changes create short-term power demands that can significantly exceed the continuous supply requirement - and a power supply dimensioned purely for continuous output may lack the headroom to handle these transients without tripping protection or causing supply interruptions.
The EDAC Power EP190A Series addresses this directly. Built into an enclosed chassis measuring just 245 mm × 141.5 mm × 29 mm, it delivers 900 W of continuous 48 V DC output and supports a 1,500 W peak load sustained for up to 5 seconds. The fanless, conduction-cooled design requires no mechanical airflow, enabling installation in sealed or noise-sensitive environments without compromising the power headroom that demanding industrial loads require. FORTEC Switzerland offers the EP190A Series as part of its power supply portfolio.
1,500 W Peak Output for Startup and Transient Load Management
Many industrial loads draw significantly higher current during startup than during steady-state operation. Motor drives, robotic actuators, and automated machinery with high startup currents are typical examples. A power supply rated only for its continuous output level may trigger overcurrent protection at the moment of highest demand, causing system faults rather than supporting normal operation.
The EP190A's 1,500 W peak capability - 66% above its 900 W continuous rating - provides the additional power headroom needed to absorb these transient demands cleanly. This allows system designers to select the EP190A based on the continuous load requirement while retaining confidence that startup and short-term peak demands are covered without requiring an oversized supply for steady-state operation.
29 mm Profile for Installation in Space-Constrained Equipment
At only 29 mm in height, the EP190A occupies a fraction of the vertical space required by conventional high-power enclosed supplies. In industrial equipment with high internal component density and limited installation height - such as compact automation controllers, rack-integrated systems, or equipment designed to minimise overall chassis depth - this profile directly enables higher functional density without a system redesign.
Fanless Conduction Cooling - Reliability Without Moving Parts
The EP190A operates without a fan, managing heat through conduction to the host chassis rather than forced air. This eliminates the most common mechanical failure point in power supplies and removes the noise contribution of fan operation - relevant in environments where acoustic output is monitored or constrained.
Conversion efficiency of 92-95% across the operating range minimises the heat generated per watt of output, reducing the thermal load that the conduction path must handle and contributing to reliable long-term operation.
