EETimes Europe cannot be held responsible for the claims and statements made by the manufacturer. Note: The above text is the public part of the press release obtained from the manufacturer (with minor modifications). The HU-28 is housed in a standard half brick package measuring 2.28” x 1.45” x 0.5” whereas the HUL-28 is housed in a standard quarter brick package measuring 2.28” x 1.45” x 0.5”. The operating temperature range is -40 to 100✬, and the MTBF per MIL-STD-217F is in excess of 350000 hours. Both units can provide up to 200 Watts of hold up output power, the isolation between the baseplate and input is 700VDC. The switching frequency of the HU-28 and HUL-28 is 310Khz, reflected ripple is 40mA peak to peak. The response time for both modules is 5µs. The mode of operation is determined by the value of the input voltage in relation to the preset trip voltage.
When tripped, the module stops charging the hold up capacitors and connects them to the Vout pins. There are two modes of operation: 'standby' and 'tripped', during stand by, the module charges the hold up capacitors to 45V and maintains that voltage. Both modules have an input range of 15.5VDC to 36VDC and offer a user programmable hold up trip voltage.
