Osram Sylvania Lights the Way With Acopian’s Mini Encapsulated Power Supplies

For more than 100 years, Osram Sylvania has been lighting the way with innovative lighting products and services for virtually every industry. From LEDs, incandescent, halogen and fluorescent lighting to light management systems, service and maintenance, Osram Sylvania is an industry leader in lighting solutions.

Acopian is happy to shine light on Osram Sylvania’s products and services by supplying them with our AC-DC Mini Encapsulated Linear Power Supplies.

These modules have series regulated outputs ranging from 1V to 75V and as high as 2.5A. Their footprint is only 3.5 x 2.5 inches, making them ideal for smaller applications. Output power range is 0.5W to 14W. These modules have a thermal barrier running through the power supply, isolating the hot running components from the more sensitive components.

Universal input range is 105-125 VAC, 47 to 420 Hz, single phase. Output ripple/noise is1mV. All models may be used in series and are short circuit (continuous) protected.

Duke Energy Acopian has the 1U Need

Posted by Acopian Power Supplies on March 28, 2014

Duke Energy is one of the largest electric power holding companies in the US, making lives better for more than 7 million customers by providing electric and gas services. Based in Charlotte, North Carolina, keeping the lights on for so many people is no small feat - and requires reliable employees, reliable services, and reliable power supplies.

Acopian is proud to provide reliable, 1U AC-DC programmable power supplies to Duke Energy.

Most notably, these power supplies are available in 135 different voltage ratings from 1 Vdc to 135 Vdc and feature current ratings up to 40 A. This new family of power supplies is engineered specifically to satisfy the requirements of OEM, industrial and laboratory applications, from automated test equipment, product development and industrial controls to water purification and electro plating. They are also ideal for ATE, OEM and laboratory applications such as component testing, semiconductor burn-in, test and measurement, RF Amplifiers, LED/laser testing and a variety of electromagnetic and electromechanical applications.

All models within this latest family of power supplies are PFC, universal input, built-in over voltage protection (OVP) and constant current control. Standard features include short circuit and overload protection, "soft start" and "no load" operation, internal EMI filtering, thermal protection, remote sensing and RFI shielding. Options for the 450W 1 U single-output supplies include fixed auxiliary output of between 3.3Vds and 125Vdc up to 180W, digital LED voltage and current meters, voltage and current monitor outputs, provisions for N+1 redundancy, and digital interfaces.

Acopian Adds New Array of Options to Low-Profile Family of AC-DC and DC-DC Power Supplies

Acopian has added new options to enhance the Low Profile Family of AC-DC and DC-DC Power Supplies. At just 1.7 inches tall, the UL recognized, CE certified low profile models are ideal drop-in replacement for existing supplies for applications in which weight, efficiency, size or wide input range tolerance is a factor. They’re commonly used for LED signage and lighting, industrial controls, power and energy, aerospace, nuclear and electrolysis applications.

Now both the 720W single-output and 750W wide-adjust output models are available with the option of a thermostatically controlled fan, which runs at a reduced speed until maximum speed is required. They also come with options for an output blocking protection diode for batter charging or redundant applications, three-phase 208VAC or 170-240VAC (60-400 Hz) input voltage, 15VDC/100mA auxiliary voltage and provisions for N+1 redundancy and paralleling for higher current.

They may be small, but they sure are mighty. Order yours online: 720W single-output units and 750W wide-adjust output units.

Power Supply DIY: Design-it-Yourself

Posted by Acopian Power Supplies on March 06, 2014

Acopian’s newly expanded Online Custom Power Supply System Builder allows engineers to design their own custom system to fit an array of outputs, power levels and voltages. It was developed to meet the demand for fast delivery of customized systems at off-the-shelf prices. Through a series of easy-to-follow steps, you can design DC-DC and AC-DC power supplies, high voltage power supplies, redundant systems and unregulated power supply systems.

The online tool allows you to design a unit with 1 to 30 outputs in a range of voltages (0V-30KV) and currents (0.025W-2400W). You can also choose any physical configuration, as well as select options for over-voltage protection, remote sensing or enclosure type. Take customization to the max with sophisticated sequencing control options, colored LED output indicators, screwdriver or knob output adjustment and test-point styles.
