The compact CUS500M1 series of single output AC-DC power supplies are available with 12V, 19V, 24V, 28V, 32V, 36V and 48V outputs in an industry standard 3 x 5 inch package and can deliver 500W with forced air cooling or 300W with 500W peak power when convection cooled.
CUS500M1 can be used in both Class I and Class II (no earth wire) applications and offers efficiencies of up to 96%. A cover with integral end mounted fan option is available.
Safety certifications include IEC/EN/ES 60601-1 and IEC/EN/UL 62368-1 with UKCA and CE marking for the Low Voltage, EMC and RoHS Directives. The units also comply with EN 55011-B and EN 55032-B conducted and radiated emissions, and meet the EN 61000-3-2 harmonics, IEC60601-1-2 Edition 4 and IEC 61000-4 immunity standards.
Typical applications include medical (B and BF type), home healthcare, dental, test and measurement, broadcast, professional audio and industrial equipment.
This extensive series covers a wide range of industrial and medical applications, including models utilising amorphous core technology that protect against damaging high voltage pulses. With current ratings of 0.5A to 1,000A, the series is available with 250V single phase or 500V three-phase inputs. DIN rail (up to 30A) or chassis mounting case styles are offered, along with a choice of standard or medical leakage versions.
The series comprises of 300W (3U high half-rack) and 1,000W (3U high full-rack) power levels and either a 120Vdc or 500Vdc maximum rating. The units operate in 7 different load modes and 4 operating modes. This allows the user to perform up to 17 different load tests on DC power supplies, fuel cells, solar cells, batteries and components to fully characterise their performance.
The loads can be programmed for multiple load types, including constant current, constant resistance, constant power, external control, short circuit, and constant voltage with a current limit. The operating modes are normal, pulsed load (dynamic time and frequency), complex waveform generation and "sweep" to test and determine a product's voltage-current, overcurrent or power limit characteristics. Eight load settings can be stored internally.
Up to 10 units may be paralleled in a master-slave arrangement for higher power requirements. Multiple SFL loads can also be connected to separate devices for synchronised load control and dynamic operation. The series can be programmed using analogue or digital signals, with an optional ripple and noise measurement and IEEE interface.
The CUS350MP-1000 AC-DC power supplies are rated at 350W continuous and 1000W peak power output with convection cooling for applications requiring low audible noise or 500W continuous, 1000W peak power with forced air. The series is certified to IEC60601-1 3rd edition (medical), IEC62368-1 and IEC62477-1 (OVCⅢ) with compliance to the EN60601-1-2:2015 Edition 4 immunity requirements. With efficiencies of up to 94%, waste heat is reduced allowing the power supply to operate reliably in a compact 88 x 183 x 44mm package size. A 5V 0.3A standby voltage and remote on/off are fitted as standard. The high peak power rating makes the CUS350MP-1000 suitable for use in printers and other equipment utilizing DC motors.
The 500W, 1U, single output XMS500A is available in either class I or class II configurations. Both versions achieve class B EMC performance (both conducted and radiated) to EN55011 and EN55032. The whole range is certified for both industrial and medical equipment with BF ready medical isolation (1 x MOPP input / ground, 2 x MOPP input / output and 1 x MOPP output / gnd). Other features include a selection of standby and fan supplies, various case and fan options (including top fan for very low audible noise), remote on/off and dual or single fusing.
