n + 1 redundancy between multiple power supplies. This ensures the availability of all process and safety systems in the event of a fault. The innovative design removes the requirement for an additional external redundancy module, reducing cost and saving space. Special plug-in connectors allow hot-swap replacement of the devices during operation, using the sequence described in the data sheet. According to the company, the
The CP20.245-R2 has optimal electronic and
mechanical design for the harsh environmental conditions found at sea and onshore. Not only is it characterised by its high immunity to transients and voltage peaks, but it has a robust aluminium housing and provides full output power of 480W, even with fluctuating ambient temperatures between -40˚C and + 60˚C. The extensive approval package includes Marine DNV, Marine ABS and ATEX, among others. High systemreliability is assured thanks
to an integrated decoupling feature, which is said tomake the CP20.245-R2 unique. An onboard decouplingMOSFET enables a safe 1 + 1 and
The nine new series
(LCW15, LCW25, LCW35, LCW50, LCW75, LCW100, LCW150, LCW200 and LCW320) offer power levels from 15W to 320W.
The input voltage range of the LCWseries is
from85 to 305VAC, satisfying global regulatory requirements and suiting nominal inputs from 100VAC to 277VAC, with the 150W, 200Wand 320Wmodels featuring active PFC. Depending on power level, the LCW series
is available with nominal outputs ranging from 3.3V to 48V; and they offer an operating temperature range of -30˚C to +70˚C.
high efficiency of 95.2%ensures low power losses and little waste heat. In addition, the 20%power reserve fromthe basic version ismaintained. The compact product with a width of only 48mmhas been retained despite the additional, application- specific features, the company explains. For remote status monitoring, two relay
contacts for DC-OK and alarm signals are provided. Two additional inputs allow the power supply to be put into an energy-saving standby mode using the remote ON / OFF function, and automatic load sharing in parallel operation for greater power output can be realised. Parallel operation ensures an optimised temperature balance between the connected power supplies, prolonging the service life of the devices. All CP20 versions have a compact housing with dimensions of 48 x 124 x 127mm (WxHxD).
The DP800(A) series was launched in 2013 with four
differentmodels.With the new DP813(A) and DP822(A), the company has enhanced the DP800(A) series with two versions which can providemuch higher current. The previousmaximumcurrent of 10 Ampère is now extended in DP813(A) to 20 Ampère and in DP822(A) to 16 Ampère. DP813(A) has one output channel and can be used in two different ranges. In low-rangemode the device can output up to 8 Volt/20 Ampère and in high range mode up to 20 Volt/10 Ampère. DP822(A) has two channels, and the first channel can be adjusted up to 20 Volt/5 Ampère and the second channel up to 5 Volt and 16 Ampère. Both versions provide a sense channel on the high current output to detect the voltage drop at the test cables, which has a significant influence to the test setup at higher current. All current and voltage values can be increased by
10%with eachmodel (except DP822(A)). For example, with DP832(A) series the values at channel 1 and 2 can be increased to 33 Volt and 3.3 Ampère.With the high current output of DP822(A) a 5 % increase to 16.8 Ampère is possible. All devices can be operated in constant current (CC) or in constant voltage (CV)mode. The devices have a very clean power output
based on the very low ripple and noise of<350 mVrms/3mVpp and can be used for applications where such clean power is required. Furthermore, the line and load regulation is very stable with <0.01 % +2 mV/+250µA.
The new additions join five cells that are available
off-the-shelf to help OEMs meet more common space requirements. Thin Cells are in demand for professional and consumer applications where a non-rechargeable high energy, slim and safe battery is required – such as handheld devices used in asset tracking, data logging and smart security, as well as wearable devices used in medical environments for remote patient monitoring. Each Thin Cell boasts a high energy density, provides a stable 3V discharge and utilises Ultralife’s medical and military proven lithium manganese dioxide (Li-MnO2) chemistry. The new additions include: the CP114951, with a 51.0 x 48.8mm footprint with a 1.1mm
thickness and a 0.38Ah nominal capacity; the 30.0 x 11.2mm and 3.2mm thick CP301030; and the CP301322, which is the most lightweight addition with its 22.5 x 13.5mm footprint, 3.2mm thickness and 1.1g weight. The CP603145, meanwhile, measures 45.0 x 31.0mm, 6.2mm thickness and 15.7g weight. This
slightly larger footprint is coupled with a higher operating temperature range from -20 to +80˚C (compared to -20 to +60˚C for the other three cells).
