PRODUCT DESCRIPTION

100-240 Vac, 24 V, 960 W

3 year warranty

SHORT-FORM DATAPLANET power supplies are the top-of-the-line
industrial grade DIN rail power supplies from
PULS. Compact size, high efficiency and dynamic
BonusPower capabilities make the PLANET power
supplies stand out.
Thanks to the integrated dynamic BonusPower
management, the power supply adapts to varying
power demands in real-time. By continuously
monitoring the power output through a powertime integral, it provides extra power for different
durations. For example, the power supply can deliver
110 % of its rated power for 30 seconds or up to
150 % for 5 seconds at temperatures up to +60 °C.
At temperatures up to +45 °C, it can continuously
provide 120 % of its rated power. This flexible power
management ensures that the power supply meetspeak demands without being constrained to fixed
power values, enhancing overall performance andreliability.
The high efficiency from stand-by to full load reduces
total cost of ownership and carbon dioxide emissions,with particularly low power losses during no-loadconditions.
Robust against back-feeding events, PLANET power
supplies minimise downtime and ensure safety andreliability with HiccupPLUS mode in case of overload.

Installation Instructions
DANGER–––––

Risk of electrical shock, fire, personal injury or death.

Turn power off before working on the device. Protect against inadvertent re-powering.
Do not open, modify or repair the device.
Use caution to prevent any foreign objects from entering the housing.
Do not use in wet locations or in areas where moisture or condensation can be expected.
Do not touch during power-on, and immediately after power-off. Hot surfaces may cause burns.

Obey the following installation instructions:This device may only be installed and put into operation by qualified personnel. This device does not contain serviceableparts. The tripping of an internal fuse is caused by an internal defect. If damage or malfunction should occur during
installation or operation, immediately turn power off and send unit to the factory for inspection.
Install device in an enclosure providing protection against electrical, mechanical and fire hazards. Install the device onto a
DIN rail according to EN 60715 with the input terminals on the bottom of the device. Other mounting orientations requirea reduction in output current.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper cables that aredesigned for a minimum operating temperature of +60 °C for ambient temperatures up to +45 °C, +75 °C for ambient
temperatures up to +60 °C and +90 °C for ambient temperatures up to +70 °C. Ensure that all strands of a stranded wire
enter the terminal connection.
Unused screw terminals should be securely tightened.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or frost is allowed. The
enclosure of the device provides a degree of protection of IP20.
The isolation of the device is designed to withstand impulse voltages of overvoltage category III according to IEC 60664-1.
The device is designed as “Class of Protection I” equipment according to IEC 61140. Do not use without a proper PE(Protective Earth) connection. The device is suitable to be supplied from TN-, TT- and IT- mains networks. The voltage
between the L or N terminal and the PE terminal must not exceed 300 Vac continuously.
A disconnecting means shall be provided for the input of the device.
The device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do notcover ventilation grid!
The device is designed for altitudes up to 5000 m. See additional requirements in the product datasheet for use above
2000 m.
Keep the following minimum installation clearances: 40 mm on top and bottom, 5 mm left and right side. Increase the 5
mm to 15 mm in case the adjacent device is a heat source. When the device is permanently loaded with less than 50 %,the 5 mm can be reduced to zero.
The device is designed, tested and approved for branch circuits up to 32 A (IEC) and 30 A (UL) without additional protection
device. If an external fuse is utilized, do not use circuit breakers smaller than 16 A B- or C-Characteristic to avoid a nuisancetripping of the circuit breaker.
The maximum surrounding air temperature is +70 °C. The operational temperature is the same as the ambient or
surrounding air temperature and is defined 3 cm below the device.
The device is designed to operate in areas between 5 % and 95 % relative humidity.

All parameters are specified at 24 V, 40 A, 230 Vac, +25 °C ambient and after a 5 minutes run-in time unless otherwise noted.

BonusPower short term:
The power supply is designed to support loads with a higher short-term power requirement without damage or shutdown.
The short-term duration is hardware controlled by an output power manager. This power is repeatedly available.

3)

HiccupPLUS mode:
At heavy overloads (when output voltage falls below 13 V), the power supply delivers continuous output current for 2 s. After this, the output isswitched off for approx. 18 s before a new start attempt is automatically performed. This cycle is repeated as long as the overload exists. If theoverload has been cleared, the device will operate normally, see Fig. 6-3.

10. 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.

11. MTBF
MTBF stands for Mean Time Between Failures, 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 lifetime of a product.
The MTBF figure is a statistical representation of the likelihood of a device to fail. An MTBF figure of e.g. 1 000 000 h meansthat statistically one unit out of 10 000 installed units will fail every 100 h. 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 Failures) value is the same value as the MTBF value.

The output voltage is floating and has no ohmic connection to the ground.
Type and factory tests are conducted by the manufacturer. Field tests may be conducted in the field using the appropriate
test equipment which applies the voltage with a slow ramp (2 s up and 2 s down). Connect all input-terminals together
as well as all output poles before conducting the test. When testing, set the cut-off current settings to the value in thetable below.

helps to avoid situations in which a load starts unexpectedly or can not
be switched off when unnoticed earth faults occur.

When testing input to DC-OK ensure that the max. voltage between DC-OK and the output is not exceeded (column D). We recommend
connecting DC-OK pins and the output pins together when performing the test.
