Notes:
1. The specified maximum capacitive load is for each output.
2. When measuring cross regulation, the load on one output is varied from 25% to
100% while the other output is held at 100%.
3. When measuring output ripple, it is recommended that an external 0.1
µF
ceramic
capacitor be placed in parallel with a 10
µF
electrolytic capacitor from the +V
OUT
pin to the -V
OUT
pin for single output units and from each output to common for
dual output units. This is illustrated by capacitors C
6
and C
7
in the typical con-
nection diagram at right.
4. Transient recovery is measured to within a 1% error band for a 75% - 50% - 25%
load change.
5. Output overload protection is provided by a “hiccup mode” circuit with auto-
recovery.
6. The input capacitors shown in the connection diagram (C
2
, C
3
& C
4
) are used on
110V input models to achieve 79 dBµV from 0.15 - 0.5 MHz and 73 dBµV from
0.5 - 30 MHz. They are ceramic, 1
µF,
250V capacitors and should be mounted
as close to the unit as possible.
7. To meet the EFT and surge requirements of EN 50121-3-2, an external input
capacitor is required, as shown in the connection diagram at right (C
1
). For the 24
V
IN
models a single 330
µF/100V
electolytic capacitor is recommended. For the
110 VIN models, two 100
µF/250V
electrolytic capacitors connected in parallel
are recommended.
8. Operation at no-load will not damage these units. However, they may not meet
all specifications.
9. It is recommended that a fuse be used on the input of a power supply for protec-
tion. See the table above for the correct rating.
Recommended Input/Ouput Components
Remote ON/OFF Control
All models of the
MR08xxx-RUI
series include an on/off control input (Pin 1). This input uses positive logic to enable/disable
the unit. When the input is “high”, the unit

operates, when it is “low”, the unit is off.
The chart at right gives the specifications
Unit Off

1.2
VDC
for the control input. In the diagram above,
Off Idle Current

mA
an open collector switch is used (Q
1
). The
Control Common Referenced To Negative Input
(Pin 2)
control input should be left floating if it is not
being used. Shorting the control pin to the -V
IN
input (pins 2 & 3) will turn the unit off.
