RACM1200-V

The RACM1200 series is a Europe-designed, manufactured baseplate-cooled, highly efficient power supply series. The compact, single output AC/DC converters are just 228 x 96.2 x 40mm (9.0” x 3.8” x 1.6”) in size and can deliver 1000 watts continuously with the baseplate held to 80°C while 1200 watts is available for up to ten seconds or continuously with airflow. Input is universal 85-264VAC, dip-switch adjustable outputs available are nominal 24, 48 followed by 36VDC soon and efficiency is 95% peak. An isolated and ‘always on’ 5V/1A auxiliary supply is provided along with an adjustable 5 to 12V/1A system fan output, with all outputs isolated from ground to 2kVAC for PoE applications. The power supplies hold safety certifications for industrial, ITE, and medical with 2 MOPP isolation and low leakage current for BF applications. The products also meet Ecodesign requirements for standby losses and comply with radiated and conducted ‘Class B’ EMI emissions limits.

130W AC/DCs in 2”x4” format suit wide applications

The RACM130E-K series in the industry-standard 2” x 4” footprint, is aimed at applications that are cost-sensitive, but still require high performance and highest levels of safety certification. The parts operate from 85 to 264Vac with tightly regulated single outputs including 12V, 15V, 24V, 36V and 48VDC, providing 130W output power peak, or continuously with airflow. Efficiency is high, around 90% and this is maintained down to light loads for ErP compliance. No-load losses are also low at less than 200mW at 230Vac. Safety certifications include 2MOPP/250Vac medical for ‘B’ or ‘BF’ applications to IEC/EN/ANSI/AAMI ES 60601-1, as well as IEC/EN 62368-1, IEC/EN 60335-1 and IEC/EN 61558-1 for industrial, test and measurement, IT and household use, all to 4000m altitude. On-board dual input fusing is included.

90W 2”x4” AC/DCs are versatile

The specifications of the RACM90-K have not been compromised, however, with the parts featuring a wide 85-264VAC input range, tightly regulated single outputs including 12V, 15V, 24V, 36V, and 48VDC, and an operating temperature range from -40°C to +90°C with derating. Safety certifications include 2MOPP/250VAC to IEC/EN/ANSI/AAMI ES 60601-1, ‘B’ and ‘BF’ compliant with dual input fusing for medical applications, as well as to standards for reinforced isolation for industrial, test and measurement, ITE and household use, all to 4000m altitude. The parts are classified as Limited Power Source (LPS) and are suitable for installation in surge Class 3 and overvoltage category OVC III environments. Additionally, EN 55032/35 ‘Class B’ emissions limits are met with a large margin. Efficiency is high and is maintained down to light loads, complying with ErP requirements, and no-load consumption is less than 200mW at 230Vac.

15W and 25W AC/DCs operate to 528VAC in harsh conditions

The new cost-effective, board-mount AC/DC converters rated at 15W and 25W are the RAC15-K/480 and the RAC25-K/480, with an input range of 85-528VAC. The products build on the success of RECOM’s RAC05-K/480, a 5W AC/DC with the same ultra-wide input range. Outputs available are 5V, 12V, 15V and 24V, fully protected against short circuits, over-current and over-voltage. The Parts are certified as Limited Power Source (LPS) according to IEC 62368-1 and can be used in over-voltage category III (OVC III) applications in pollution degree 3 (PD3) environments up to 5000m altitude. Certification to IEC/EN 61010 is also held and the parts are EN 55035 and EN 55032 Class B EMI-compliant, with floating outputs. Efficiency achieved is high, up to 87%, allowing operation from -40°C to 70°C ambient without derating (60°C for the RAC15-K/480) and to 90°C with reduced power.
