Description
The EMS Series of DC-DC converters provide a single isolated step-down voltage (3.3 or 5 VDC nominal) from a
wide-input voltage range (18 – 60 VDC). The EMS is an excellent choice in applications where multiple input
voltage options are required. The designer can use a single EMS converter to cover both 24Vin and 48Vin input
ranges, eliminating the need to specify multiple modules to handle each input range. This is particularly useful in
wireless base station applications where the power plants tend to vary and could provide nominal 24 or 48 V input.
The EMS converters are highly efficient over the entire wide-input voltage range, cost-effective, and offer a low
profile, industry-standard quarter-brick footprint. The standard feature set includes remote on/off, remote output
voltage sensing, industry standard output trim, input undervoltage lockout, and overtemperature shutdown with
hysteresis.
