OUTPUT
POWER
(MAX.)
Measurement Bandwidth: 20 MHz; Measured with 1 µF ceramic and a
330 µF (470 µF for 12 V output model) aluminum or solid tantalum
capacitor across the output terminals.
Di/dt = 1 A/µs; ∆I
with a 1 µF ceramic and a 330 µF (470 µF for 12 V output model)
aluminum electrolytic capacitor across the output.
External input fusing required. Use a fast acting fuse: 40 A (24 V model),
15 A (48 V, 350 W model).
Iout = Iout (max) Measured with the input capacitor, Cbypass = 330 µF,
and 6 µH inductor in series with the power source. Frequencies
>100 kHz.
Signal line assumed <3 m in length.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand-alone product.
Negative remote ON/OFF option also available. Add suffix ‘-R’ to part
number, for example see part numbering system.
With the enable signal asserted, this is the time from when the input
current reaches 10 % of the final steady state value until the output
voltage reaches 10 % of the nominal output value. Start-up into resistive
load.
With Vin > Vin (min.) applied for a minimum of 1 second, this is the time
from when the primary ON/OFF signal is activated until the output
voltage reaches 10 % of the nominal output voltage.
Minimum effective ESR is 1 mΩ. Minimum phase margin is 35º.
Measured per ETSI 300 132-2 Section 4.7.2.
From 10% to 90% of Vout (nom). Full resistive load. 1 µF ceramic and
330 µF (470 µF for 12 V model) electrolytic capacitors across the output.

Minimum effective ESR is 1 mΩ. Minimum phase margin is 35º.
Measured per ETSI 300 132-2 Section 4.7.2.
From 10% to 90% of Vout (nom). Full resistive load. 1 µF ceramic and
330 µF (470 µF for 12 V model) electrolytic capacitors across the output.
Converter guaranteed ON for positive option.
Maximum driver leakage to insure converter is ON.
Converter guaranteed OFF for positive option.
Driver sink current @ Vrc ≤ 1.2 V.
0.40 in height option is not available on the 12 V output model.
