This series provides 12, 15, 18, 24, 28, 36, 48, 53 Vdc single output voltage. The output voltage can be easily adjusted up to ±8% with the integrated potentiometer. They have the following protection functions: over-voltage protection (latch mode), over-current protection (hiccup mode and auto-recovery), short-circuit protection (continuous and auto-recovery) and over-temperature protection (sensed by an internal thermistor; hiccup mode and auto-recovery).

MAD180 series is equipped with long-life electrolytic capacitors, operate with efficiencies up to 94%, provide power factor correction of 0.95, have a no-load power consumption of 150 mW max, and are built to IEC protection types of class I and class II. The power supplies can be operated at an altitude up to 5,000 m and with their superior performance at an operating temperature of -40 to +85°C.

The MAD180 power supplies have been certified to the following standards:
Safety approvals: IEC/EN/UL 62368-1
IEC/EN/ANSI/AAMI ES 60601-1
Conducted emissions: EN 55032 Class B
Radiated emissions: EN 55032 Class A

The MAD180 has the most compact design within the same power range of power supplies and is a candidate for medical diagnostic equipment such as MRI scanners, laser treatment equipment, X-ray and patient monitoring etc. Product warranty is 5 years.

Energy is stored in electrolytic capacitors, replacing the need for batteries and their associated maintenance and servicing. A remote on/off function can be activated to avoid an unsafe discharge of stored energy. The charge and discharge status can be monitored locally or remotely via a dc OK relay, an LED indicator and photo-coupled signals. If a longer hold-up time is desired, modules can be connected in parallel. The 24-V model has a switch that can be used to select either fixed or variable voltage buffer levels. In fixed mode, it will provide power
when the input voltage drops to 22.4 V, in variable mode when the input decreases by 1 V.

Measuring 175x85x57 mm (LxWxH), the units will operate without derating in ambienttemperatures of -25 to +70°C. The five-year warranty ZBM20 has protection against both input overvoltage and overcurrent conditions, has inrush current reduction and internal fusing. Safety certification includes IEC/UL/CSA/EN 62368-1 with CE marking to the Low Voltage, EMC and RoHS Directives.
