For effi cient, fully isolated DC power in the smallest space, the UCE
open frame DC/DC converter series fi t in industry-standard “eighth
brick” outline dimensions and mounting pins (on quarter-brick pinout).
Units are offered with fi xed output voltages from
1.5 to 12 Volts and currents up to 30 Amps. UCEs
operate over a wide temperature range (up to +85
degrees Celsius at moderate airfl ow) with full rated
power. Interleaved synchronous rectifi er topology

electrical performance in a through-hole package.
Overall noise is typically 50 mV pk-pk (low voltage
models) with fast step response. These converters
offer tight output regulation and high stability even
with no load. The unit is fully protected against
input undervoltage, output overcurrent and short

... If the short-circuit condition persists, another shutdown cycle will initiate. This rapid on/off cycling is called “hiccup mode.” The hiccup cycling reduces the average output current, thereby preventing excessive internal temperatures and/or component damage. The “hiccup” system differs from older latching short circuit systems because you do not have to power down the converter to make it restart ...

... Output Capacitive Load These converters do not require external capacitance added to achieve rated specifi cations. Users should only consider adding capacitance to reduce switch- ing noise and/or to handle spike current step loads. Install only enough capaci- tance to achieve noise objectives. Excess external capacitance may cause regulation problems, slower transient response and possible instability ...

... The airfl ow collimator mixes the heat from the heating ele- ment to make uniform temperature distribution. The collimator also reduces the amount of turbulence adjacent to the UUT by restoring laminar airfl ow. Such turbulence can change the effec- tive heat transfer characteristics and give false readings. Excess turbulence removes more heat from some surfaces and less heat from others, possibly causing uneven overheating ...
