Voltage tolerance includes initial setting, line and load regulation. Ripple/noise is measured with 20 MHz bandwidth, a 12-inch twisted-pair lead, and 0.1 µF plus 47 µF capacitors in parallel at the output.
Observe voltage, current, rated-power and derating limits together. Maximum voltage and maximum current are not unrestricted simultaneous operating points. Use only the local or external adjustment available on this construction.
Factory voltage, current and printed power are separate catalogue entries; their rounded product does not replace the maximum-power limit.

57.6 V
Default float charge voltage
55.2 V
Rated charging current
40 A
Battery-capacity reference
120–400 Ah
Factory charging profile
Three stages
Three-stage charging uses constant current, constant boost voltage and then float. The two-stage curve omits float. The illustrated completion/float transition is at 10% of charging current.
The charging table lists open and sealed lead-acid batteries. The programmable description also covers lithium-ion types, including lithium iron phosphate and lithium manganese. Confirm all voltage, current, stage and timeout settings with the battery manufacturer; the suggested Ah range is not permission to exceed its charging-current limit.
Use the separately selected MEAN WELL SBP-001 smart battery-charging programmer with a PC, or the actual fitted communication protocol, to configure curves and timeout parameters.
Power-supply and charging currents are different mode ratings. Do not substitute one for the other or replace the printed power limit by multiplying rounded charging-table values.

Typical input current
13.3 A at 115 VAC; 11 A at 230 VAC; 9.3 A at 277 VAC

Set-up / rise time
1800 / 100 ms at 230 VAC, full load
Typical hold-up time
12 ms at 230 VAC, full load
Unless otherwise stated, specifications are measured at 230 VAC, rated load and 25°C ambient. Active PFC is built in. Apply the input-voltage derating curve; the input range does not guarantee full output at every voltage.
Set-up and rise times refer to the first cold start. Rapid repeated switching can increase rise time.
Protection and Recovery

105–115% of rated output power
Overload recovery
Constant-current limiting, then output shutdown after 5 seconds; reapply AC power
Short-circuit protection
Constant-current limiting, then output shutdown after 5 seconds; reapply AC power
Over-voltage protection
59–69.1 V; shutdown, reapply AC power
Over-temperature protection
Shutdown; automatic recovery after cooling
Auxiliary Output, Control and Status
Auxiliary output
12 V, 0.5 A, ±10%; maximum ripple 150 mVp-p
Auxiliary behaviour
Available independently of remote main-output ON/OFF
Remote ON/OFF
Short Remote ON/OFF to +12 V AUX for ON; open for OFF
DC OK relay
Closed when normal; open during alarm
AC Fail relay
Closed when AC input is normal; open during alarm
Temperature Alarm relay
Open when normal; closed during alarm
Relay contact rating
30 V maximum, 1 A maximum resistive load
AUX is a separate control supply. Do not add its current to the main output rating. Its GND-AUX return is isolated from the main DC output.
This order code supports PMBus. Use its manufacturer protocol manual for addresses, commands and bus parameters; PMBus, CANBus and RS-485 are not interchangeable interfaces.
In power-supply mode green indicates normal output and red indicates protection. During charging, orange indicates stages 1/2, green indicates float/stage 3, and red indicates protection or charging timeout. Flashing red is the approximately 95°C internal-temperature warning while output remains operating; it is not an ambient-temperature rating.

Connector ampere limits do not add power capacity. Keep combined outputs within 2304 W and the selected voltage/current limits. Charging is limited to 40 A; a 50 A connector does not increase charging current.
For remote ON/OFF, short pin 2 to AUX pin 4 for ON and leave it open for OFF. Relay references are separate from the AUX return. Use the listed ALTW assemblies or suitable equivalents, maintain polarity, and seal unused ports with the appropriate optional caps.

For operation above 2000 m, reduce the permitted ambient temperature by 3.5°C for each additional 1000 m for this fanless supply. Follow the stated orientation and mounting clearances.
Horizontal mounting permits full load through +40°C and reduces to 60% at +60°C. Vertical mounting permits full load through +50°C and reduces to 60% at +70°C. Do not extend the horizontal curve beyond its plotted +60°C endpoint.
The 60 Hz input curve shows 50% load at 90 VAC, 60% at 115 VAC and full load from 220 through 305 VAC. Apply input and temperature derating together.
The catalogue life reference is at least 55,000 hours when the marked case temperature Tc is approximately 80°C or less. The temperature-dependent life plot is a design reference, not a warranty extension.
The charging specification lists storage at −40 to +80°C; the power-supply specification lists −40 to +85°C. Use the applicable mode specification.
