Based on a robust platform, the design of the units has been optimized to offer a very good price/performance ratio for medical applications requiring a high-quality power solution. The PJMA series is available in four output voltages: 12, 24, 36, and 48VDC.
Medical applications require robust and highly reliable power supplies capable of operating worldwide and meeting safety standards. Drawing on many years of experience, COSEL's power designers have developed an optimized platform to offer an excellent price/performance ratio without compromising quality and reliability. The PJMA series can operate within the so-called "universal input" range of 85 to 264VAC and has a typical efficiency of 88%.
Each unit features four individual output voltages as standard. The PJMA600F offers 12V/50A, 24V/25A, 36V/16.7A, and 48V/12.5A outputs, while the PJMA1000F offers 12V/84A, 24V/42A, 36V/28A, and 48V/21A outputs.
The PJMA series includes input current limiting circuitry, overcurrent and overvoltage protection, and thermal protection. These power supplies, known for their versatility and robustness, can operate in an ambient temperature range of -20 to +70 degrees Celsius. Depending on the final equipment mounting style and cooling conditions, power reduction may be necessary.
Designed for medical applications, the PJMA series features 2 MOPP input-to-output isolation, 1 MOPP input-to-ground isolation, and 1 MOPP output-to-ground isolation. The units are approved in accordance with ANSI/AAMI ES60601-1 and EN60601-1 3rd Edition standards.
In driven emissions testing, the PJMA series meets FCC-B, CISPR11-B, CISPR32-B, EN55011-B, EN55032-B, and VCCI-B standards. For applications requiring even lower emission levels, an additional COSEL NAC-type filter (NAC-16-472 for the PJMA600F and NAC-20-472 for the PJMA1000F) can be supplied.
To suit specific application requirements, several options are available, including protective coating (C), low leakage current (G), external potentiometer connector (V), remote control (R), remote sensing/low output voltage alarm and parallel operation (W), and low-speed fan (F4).
For enhanced durability and longevity, the PJMA series is built in a sealed galvanized steel enclosure with rear-mounted fans (one for the 600W model and two for the 1000W model). The PJMA600F measures 120 x 61 x 215 mm [4.72 x 2.40 x 8.46 inches] (width x height x depth) and has a maximum weight of 2.0 kg. The PJMA1000F measures 150 x 61 x 240 mm [5.91 x 2.40 x 9.45 inches] (width x height x depth) and has a maximum weight of 2.8 kg.
The PJMA series comes with a five-year warranty and complies with European RoHS, REACH, and Low Voltage Directives.
