II — SPECIFICATIONS
The following specifications are at nominal input voltages
at 25°C, nominal output voltage ±1% unless otherwise
specified.
INPUT:
Voltage: 100-230V a-c nominal; Range 85-264V a-c
(0 to 100% load, 0 to 50°C); 110-370V d-c. (polar-
ity insensitive; consult factory) Safety agency
approval applies only to a-c input operation.
Frequency: Nominal 50-60 Hz; Range 47-400Hz (0
to 100% load, 0 to 50°C) (at 400Hz leakage cur-
rent exceeds UL/VDE safety specification limit).
Current (nominal output at 100% load):
@115V a-c rms: 4A a-c rms max.
5A a-c max for RMW 51212K-300
@230V a-c rms: 2A a-c rms max.
2.5A a-c max for RMW 51212K-300
Inrush Current (cold start 25 °C ambient, EMI
capacitors removed):
@115V a-c rms: 30A pk max.,
@230V a-c rms: 60A pk max.
Switching Frequency: 120KHz
POWER FACTOR:
@115V a-c: 0.99 typ. (0.96 for 12V and 15V model)
@230V a-c: 0.95 typ.
STABILIZATION:
Source Effect Range (±10% change in line voltage):
1% max.
Load Effect (±40% load change from 60% load):
Primary: ±1%
12V Aux: ±3%
+12V: ±5%
–12V:
±5% (RMW 51212K-300)
Ripple/Noise (all outputs, nominal line, rated load):
<1% Vp-p (measured with 15MHz BW scope ter-
minated with 0.047
µF and electrolytic capacitors.
CAPACITIVE LOADING: ≤ 30,000µF.
TRANSIENT RECOVERY:
Load change from 20% to 100% of rated output current in
50 microseconds or more: >700mV ±4% max.
OUTPUT HOLDING TIME: Upon input interruption
the output is maintained for: 20 mS typ. (@115V a-c, rated
load).
START UP TIME:
@115V a-c: 2S max.
@230V a-c: 2S max.
OVERVOLTAGE PROTECTION: Fixed, factory set.
See Table 2. Latching will occur. Reset by cycling input
power off, then on again.
OVERCURRENT: Hiccup type, autorecovery (output
voltage returns to rated level upon removal of cause of
overcurrent). Models RMW 5-60K and RMW 51212K-300
latch off for overcurrent or short circuit; reset by cycling
input power off, then on again.
OPERATING TEMPERATURE: 0 to +50°C (start up -
0°C min.). Do not allow the power supply to become dust
covered because that will decrease the cooling efficiency
of the unit and cause insulation to deteriorate.
STORAGE TEMPERATURE: –20°C to +85°C.
HUMIDITY: 10% to 95% RH, operating and storage,
noncondensing.
COOLING: Natural convection.
ALTITUDE: 3000 meters.
MOUNTING ORIENTATION: Vertical or horizontal.
