  CUS100M E

  100W Class I and Class II 2”x 4” medical and   industrial power supplies deliver 75W in an 85°C   ambient


CUS100ME is a single output 2” x 4” AC/DC supply with IEC60601-1 3rd edition medical approval as well as IEC60950-1 and is available in four mechanical formats: Open pcb, pcb with baseplate, U channel and U channel with cover.

The power supply is rated at 100W maximum output power.

With baseplate and U channel conduction cooling assistance this rating can be achieved at up to 70°C ambient temperature and with forced air cooling of 1m/s operation up to 85°C ambient temperature is possible.

It meets class B levels for both conducted and radiated emi and is

compliant with EN60601-1-2:2015 Edition 4 immunity requirements.      

CUS100ME is suitable for both Class I and Class II installations, is available with 12V to 48V outputs and is ideal for medical and general applications that require silent operation with no fan noise.

Efficiency is up to 94%, and off load power consumption is less than 0.5W.

   QM Series

   700W - 1500W Modular power supply

The high efficiency modular QM range is available in system fan and low noise fan versions. The 3 models within the range are QM5 which is rated at 1200W high line and 700W low line and QM7 and QM8, both rated at 1500W high line and 1200W low line. Combining 1 MOPP (1.5kVac) input to ground, 2 MOPP (4kVac) input to output and 1 MOPP (1.5kVac) output to ground isolation, the entire QM range is certified for both medical equipment (making it suitable for BF (body floating) type) and industrial. High efficiency levels of up to 91% are combined with a wide selection of modules to perfectly match your requirement.

The DRB series of DIN rail power supplies up to 480W  

TDK Corporation announces the introduction of two additional DRB DIN rail mount AC-DC power supplies, rated at 120W and 240W (144W/288W peak for 10 seconds).  The products have a very narrow width, providing additional space for other DIN rail mount modules.  Having efficiencies of 93%, less internal heat is generated resulting in cooler electrolytic capacitors a field life of greater than 7 years at 75% load, 230Vac input.  These models complete the cost effective 15W to 480W DRB series, making it suitable for a wide range of industrial applications including factory automation, process control and test and measurement.   

The DRB120 and DRB240 models are housed in a robust metal enclosure, measuring 124mm in height, 125mm deep and widths of 35mm and 41mm respectively.  The power supplies can operate from a wide range 85 – 264Vac input and withstand a surge of 300Vac for 5 seconds.  Both have a 24V output and feature an isolated DC OK opto-coupler signal in addition to an LED indicator.  The outputs can be adjusted from 24 - 28V to compensate for series blocking diodes or FETs in redundant configurations.   

Input to output isolation is 3,000Vac, input to ground 1500Vac and the output to ground is 500Vac.  The DRBs are convection cooled and rated for operation in -25 to +70 o C ambient temperatures (cold start at -40 o C), derating linearly above 55 o C to 50% load at 70 o C.   

The units are safety certified to IEC/EN/UL/CSA 60950-1, IEC/EN/UL 62368-1, UL 508, IEC/EN 62477-1 (OVC III), and are CE marked for the Low Voltage, EMC and RoHS2 Directives.  Both meet EN55011-B, EN55032-B, CISPR11-B, CISPR22-B, EN61204-3 (Class A) radiated and conducted emissions, and comply with the EN61000-4 immunity standards.

5kW 1U programmable DC power supply series extended with five new output configurations

TDK Corporation (TSE 6762) announces the introduction of five new models to the TDK-Lambda brand 5kW GENESYS+™ series of high power density programmable DC power supplies. This expansion now provides incremental and seamless choices in output voltage and current ranging from 0-10V/500A to 0-600V/8.5A. Initially launched in 2017, the GENESYS+™ provides higher efficiency, improved performance and is functionally compatible with existing TDK-Lambda Genesys™ and Z+ programmable power supplies. The series is suitable for use in a large number of applications, including component, automotive and aerospace testing, semiconductor fabrication, solar array and battery simulation, plating and water treatment.

All GENESYS+™ 5kW products share a common 1U high 19” (483mm) rack mountable chassis and weigh just 7kg, the lightest in the industry. The five new models are rated at 0-40V/125A, 0-60V/85A, 0-80V/65A, 0-100V/50A and 0-150V/34A with operation in constant voltage, constant current and constant power modes. The units can be configured with three phase 170 to 265Vac, 342 to 460Vac or 342 to 528Vac inputs. Up to four power supplies can be connected in parallel with an advanced master/slave system that provides dynamic load response and ripple and noise characteristics comparable with that of a single power supply.

Programming is possible using the front panel controls, remotely via LAN (LXI 1.5), USB 2.0 and RS232/485 communications, or by using the isolated analogue control and monitoring (0-5V, 0-10V) which are provided as standard.  Optional interfaces include a choice of GPIB (IEEE488.2) and the Anybus CompactCom interface platform for DeviceNet™, EtherCat, Modbus, PROFIBUS and other interface options as they are released. Software drivers, a waveform creator and a virtual front panel GUI are provided in the software package. Safety features are standard in all GENESYS+™ power supplies, providing Safe/Auto Re-Start, Last Setting Memory and built-in protection functions.

The five-year warranty series is safety certified to IEC/EN/UL 60950-1, is CE marked to the Low Voltage, EMC and RoHS2 Directive and is compliant to the industrial IEC/EN 61326-1 standard for conducted EMI, radiated EMI and EMC immunity.
