XMS500A
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.
CHVM
CHVM high voltage dc-dc converter modules offer output voltages of up to 2kV in compact SIP pcb mount formats. Output power is 1.4W to 3W depending on package and all units accept a nominal 12Vdc input. Remote on/off is standard and the output can be adjusted from 0.5% to 100% using an external variable resistor or applied voltage.
CHVM offers extremely low ripple and noise performance (as low as 5mVp_p on a 1000V output) making them suitable for precision, noise sensitive applications such as photomultiplier tubes, photodiodes and other detectors and devices often employed in laboratory equipment such as scanning electron microscopes, X-ray fluorescence spectrometers, mass spectrometers and ultrasonic probes.
ZBM20
ZBM20 modules are ideal for providing short term hold-up or peak power for loads connected to 12, 15 or 24Vdc AC-DC power supplies. They can supply an additional 380ms hold-up at up to 448W.
During normal operation, energy is stored in the ZBM20’s electrolytic capacitors. When the AC power is interrupted for a short period of time, the ZBM20 continues to power the load, allowing equipment to shut-down in a safe and controlled manner. The ZBM20-24 can be set to fixed or variable buffer mode. In fixed mode it will provide power when the input voltage drops to 22.4V, in variable mode when the input decreases by 1V. Multiple buffer modules can be paralleled for additional hold-up time. Product status can be accessed remotely via a DC OK relay, or opto-coupled signals. The output voltage can also be inhibited to avoid an unsafe discharge of the stored energy.
DBM20
The DBM module is ideal for providing short term hold-up or peak power for loads connected to a 24Vdc output AC-DC power supply. It can supply an additional 250ms hold-up at 448W output power.
During normal operation, energy is stored in the DBM20’s electrolytic capacitors. When the AC power is interrupted for a short period of time, the DBM20 continues to power the load, allowing equipment to shut-down in a safe and controlled manner. The DBM20 can be set to fixed or variable buffer mode. In fixed mode it will provide power when the input voltage drops to 22.4V, in variable mode when the input decreases by 1V. Multiple buffer modules can be paralleled for additional hold-up time. Product status can be accessed remotely via a DC OK relay, or locally using the LED indicators. The output voltage can also be inhibited to avoid an unsafe discharge of the stored energy.
i7A
The i7A series can be used to derive additional high power outputs from a 24V, 36V or 48V DC power supply, at a much lower cost than isolated DC-DC converters.
Efficiencies of up to 98.5% minimise internal losses and allow the i7A to operate in ambient temperatures of -40oC to +125oC, even with low airflow conditions. The i7A’s design provides low output ripple and excellent response to dynamic loads. Very few required external components are required, compared to discrete solutions, saving cost and printed circuit board space.
A choice of three mechanical configurations is available, measuring just 34mm wide and 36.8mm in length. The 11.5mm high open frame model is most suitable for applications requiring a very low profile. A baseplate version for conduction cooling to a cold plate is 12.7mm high, or models with an integral heatsink for convection or forced air cooling are 24.9mm high.
Standard features include an output voltage adjustment trim pin, + remote sense, remote on-off (positive or negative logic), input under-voltage, over-current and over-temperature protection.
