Specifications of a recommended external 24–VDC power supply
(regulated power supply) (The requirements of the UL 1950 standard
must be satisfied.)
Output voltage: Output voltage: 24 VDC (10% (21.6 to 26.4 V)
(Including ripple voltage and noise. See the
figure given below.)
Output current: Continuous load current must be the current
consumption level of the Power Mate i and
units or higher.
(At the maximum temperature within the
power magnetics cabinet in which the power
supply is placed)
Load fluctuation (including surge current):
The above output voltage range must not be
exceeded by any load fluctuations due to
external DO and so forth.
Instantaneous AC input disconnection hold time:
10 ms (for –100%)
20 ms (for –50%)
CAUTION
The power supplies for the Power Mate i and related units
using 24 VDC input must all satisfy the specifications
described here.
