At heavy overloads (when output voltage falls below 13 V),
the power supply delivers continuous output current for 2 s.
After this, the output is switched off for approx. 18 s before a
new start attempt is automatically performed. This cycle isrepeated as long as the overload exists. If the overload has
been cleared, the device will operate normally, see Fig. 6-2.

Lifetime Expectancy
The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by the
lifetime expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is
calculated according to the capacitor’s manufacturer specification.
The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years (131 400 h). Any number
exceeding this value is a calculated theoretical lifetime which can be used to compare devices.

MTBFMTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicatesreliability of a device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent
the life of a product.
A MTBF figure of e.g. 1 000 000 h means that statistically one unit will fail every 100 hours if 10 000 units are installed in thefield. However, it can not be determined if the failed unit has been running for 50 000 h or only for 100 h.
For these types of units the MTTF (Mean Time To Failure) value is the same value as the MTBF value.

Overview
LED Bar (E)The LED Bar is a multifunctional displaying tool. The main function is to monitor the sum of all outputs (percentages scale).
It also can display the output voltage (voltage scale) and output current (ampere scale) for the individual outputs. The
integrated Status LED displays different running conditions of the PSU in real-time.
Output Level Controls (F)The Output Level Controls consist of the Set Mode button and the UP/DOWN buttons. The Set Mode is used to change into
tripping current settings. The UP/DOWN are used to adjust different output levels or change into the Output Current Mode.
Output Controls (G)The Output Controls consist of an output LED and an Output ON/OFF button (ON/OFF) for each output. The Output LED
displays different running conditions for output in real-time. The ON/OFF is used to switch the output on/off.

Operation Settings
Monitor Output Power Mode
The Output Power Mode displays the actual total output power after startup. It is the default mode of the LED Bar. The
output Power is Displayed in percentages of 500 W. E.g. If the LED Bar is powered up till 50 %, 250 W is expended. If the
LED Bar rises above 100% and therefore exceeds 500 W the 125 %-LED flashes orange. Refer to the percentage scale on theleft sidebar.
Monitor Output Current Mode
The Output Current Mode is to check the output current of the individual outputs.
To inspect these output currents:

Press the UP or DOWN button. OUT1 in the LED bar lights up in orange. The output current is displayed in real-timein the LED Bar below. Refer to the ampere scale on the right sidebar.
In the LED Bar switch between the OUT1 - OUT4 using the UP/DOWN buttons to check the different output current
values.

Return to the Output Power Mode/default mode by pushing beyond the highest (OUT4) or lowest (OUT1) output
number.

All parameters are specified at 24 V, 20 A, 400 Vac, 25 °C ambient and after a 5 minutes run-in time unless otherwise noted.

Channel LED Signaling Overview
Below is an overview of the output LED signaling.
OFF
Output is switched OFF by ON/OFF or PSU is not powered (s. Status LED).
Green: Default
Output is switched on by ON/OFF.

Fig. 14-1: Location of outputs LEDs

Flashes green: Power budget tripped (slow rate: 250 ms ON / 250 ms OFF)Low priority outputs are tripped. Sum of output currents are above
PSU powerbudget.
Flashes green: Buttons Locked (fast rate: 125 ms ON / 125 ms OFF)No action is carried out. Button lock feature activated. Unlock buttons
by following Operation Settings > Set Button Lock. Other reason:
MOSFET protection MOSFET is >90 °C or Interval between Charge
Up/ Turn On cycles <5 s.
Orange: Pre-Alarm!

the outputs are not installed correctly. Switch OFF the output manuallyby pushing the specific output ON/OFF button.
 PSU with NEC Class II outputs: Difference between positive andnegative/Input-Output current of the output are >1 A for 6-6.5 s
 PSU without NEC Class II outputs: Connector negative wireovercurrent according to negative trip curve, or output wascontributing to negative overcurrent of another output (Ipos --- Ineg
> threshold), or High PE current (>12 A) was detected based on
overall output current sum.
Flashes orange: Short Circuit (fast rate: 125 ms ON / 125 ms OFF)
Output is tripped. The Output's output current exceeded approx. 48A.
Short circuit reasons may be electrical short, loads beyond specification,

Application Notes
23.1. Repetitive Pulse Loading
Typically, a load current is not constant and varies over time. This power supply is designed to support loads with a higher
short-term power demand (BonusPower). The short-term duration is hardware controlled by an output power manager andis available on a repeated basis. If the average load is higher than the sum of all output power, the output voltage will dip.
To avoid this, the following rules must be followed:a)

The power demand of the pulse must be below 200 of the nominal output power.

b)

The duration of the pulse power must be shorter than the allowed BonusPower time, see chapter 6c)

The average power should be lower than the nominal output power.

The R.M.S. output current must be below the specified continuous output current. If the R.M.S. current is higher, the unit
may respond with a thermal shut-down after a period of time.

23.2. External Input Protection
The device is designed, tested and approved for branch circuits up to 20 A (UL) and 32 A (IEC) without additional protection
device. If an external fuse is utilized, do not use circuit breakers smaller than 6 A B- or C-Characteristic to avoid a nuisancetrip.

23.3. Two Phases Operation
No external protection devices are required to protect against a phase-loss.
Continuous two phase operation is not recommended for this power class since
the supplying 3-phase network could become unbalanced. However, if one phase
fails, the unit may continue to operate if the load is below the power limit shownin Fig. 24-1.
Exceeding of these limits for an extended period may result in a thermal shutdown of the unit.
During power-on, some start-up attempts can occur until a permanent output
power is available. EMC performance, hold-up time, losses, and output ripple
differ from a three phase operation. Such use is not included in the approvalaccording to UL61010 and IEC62368.

Fig. 23-1: Two phase power capability

23.4. Inductive and Capacitive Loads
The unit is designed to supply any kind of loads, including capacitive and inductive loads. If extreme large capacitors, suchas EDLCs (electric double layer capacitors or “UltraCaps”) with a capacitance larger than 20mF are connected to the output,
the unit might charge the capacitor or the output might trip, chapter 6.

All parameters are specified at 24 V, 20 A, 400 Vac, 25 °C ambient and after a 5 minutes run-in time unless otherwise noted.

23.5. Back Feeding Loads
Loads such as decelerating motors and inductors can feed voltage back to the power supply. This feature is also called return
voltage immunity or resistance against Back- E.M.F. (Electro Magnetic Force).
This power supply is resistant and does not show malfunctioning when a load feeds back voltage to the power supply. It
does not matter whether the power supply is on or off.

23.6. Mounting Orientations
The device can be mounted in various mounting orientations. The listed lifetime and MTBF values from this datasheet apply
only for the standard mounting orientation. The following curves give an indication for allowed output power in different
