PWR KMB systems
1. Bas c features
Main advantage of PWR power supplies are high over-voltage category (300V/CAT IV) and wide range of
supply voltage. PWR 1 unit can be powered using single phase AC or DC voltage and PWR 3 using
three phase AC voltage.
Power supply features indication of input voltage and protection against over-voltage. Even under over-
voltage conditions power supply can be operated with limited output power. (see chapters bellow)
PWR have galvanically isolated SELV output. Multiple power supplies can be connected as follows:
• parallel: 2× higher output current, more then 2 of same type can be connected (consult with KMB)
• parallel: redundant connection with benefit of higher reliability
• serial: 2× higher output voltage
• serial with central tap: result is power supply with symmetrical output voltage ( /-)
Power supplies have U-I characteristic – from voltage stabilisation smoothly transfers to current limitation
(limitation of maximal output current).
Internal over-voltage protection of input and output is implemented. Short-circuit protection, overload and
load disconnection protection is matter of course.
Operation of the PWR unit and status of external accu. is signalled by LED and SSR output.
Supplies with external accu. Have protection against wrong connection of the accumulator and against
total discharge of accumulator.
Cooling is provided by natural flow of the air. Fan-less.
2. Safety nstruct ons
Danger of electric shock! Do not open the device.
Follow the operating instructions.
• Keep the operating instructions together with the device.
• Ensure that the device works only in perfect and original condition, in the upright position.
• Leave enough space (at least 50mm) for airflow below and above the device.
• Do not place heat sources under the unit!
• Do not use the device in an explosive areas.
• Ensure that only qualified persons operate the unit
• Only connections in this manual is permitted
• Only connect recommended external batteries or contact the manufacturer.
• Ensure that the device is not operating outside the limits. See technical data.
• Clean the machine only with a dry cloth or brush so that air vents remain clean.
If the device is used in a manner other than that specified by the manufacturer, the device protection
may be compromised.
Device may be repaired only by the manufacturer or its authorized service organization.
3. R sk assessment (ČSN EN 61010-1)
Requ rements:
The dielectric strength to be met is 300V CAT IV. This corresponds to a test voltage of 5.4 kV ~ (5 s)
resp. 3kV ~ (1min) for reinforced insulation according to ČSN EN 61010-1.
Power Module Features:
Insulation voltage is 3kV ~ (1min), overvoltage category is 300V CAT II.
Operat onal r sk w thout further act on:
2

PWR KMB systems
The insulation voltage and the certified overvoltage class are not sufficient for the required overvoltage
category. This concerns the isolation of the power circuit compared to the output terminals (DC output
voltage, external backup source and signalling).
Add t onal measures:
The input voltage of the power module is limited to 300V CAT II with an additional voltage limiter while the
device is operated in a 300V CAT IV environment.
The voltage limiter is designed with two varistors that are connected in parallel to the input terminals (ter-
minals L and N or L1, L2, L3 and N against PE). The required test 6kV / 3kA—1.2 / 50μs was performed
and the varistors are suitable for use in a 300V CAT IV environment. The supply voltage is protected by
an external fuse with the specified value and breaking capacity, type: aM 2A 500V / 120kA 10x38mm.∅
When using two varistors in parallel, it is ensured that the limit value of the overvoltage category is ob-
served even if one varistor is defective (in case of one fault).
Operat onal r sk w th add t onal measures:
As a consequence of the protective measures taken, no operational risk arises.

5. Installat on
The person installing the system is responsible for safety of whole system containing the PWR.
Installat on:
PWR is installed on DIN 35 rail in standard manner. Natural circulation of the air in the cubicle should be
ensured. Clarence of 50mm above and below PWR should be maintained.
No heat sources should be located bellow PWR.
Supply voltage:
Supply voltage have to be connected to L, N terminals resp. L1, L2, L3, N terminals through circuit
breaker. CB should be located in close distance to PWR on accessible place for operator. Circuit breaker
should be properly marked. Proper fuse and disconnecter housing should be used (i.e. OPVP10 and fuse
PVA10 2A aM, 500V/120kA, ∅10x38mm, see accessories), Alternative fuses should be consulted with
producer.
Terminals accepts 0,2÷4mm2 (24÷12AWG) wires, tightening torque 0,5÷0,6Nm.
Protection Earth, PE terminal, have to be connected with 4mm2 (12AWG) wire directly without
circuit breaker. Tightening torque 0,5÷0,6Nm.
Supply inputs are polarity free.
Output voltage:
Output voltage is on terminals and -. Terminals are doubled for easier wiring. Terminals accepts
0,2÷2,5mm2 (24÷14AWG) wires, tightening torque 0,5÷0,6Nm.
Conductors of proper cross-section have to be used depending on current and voltage loss.

Term nals for external accumulator
Accumulator is connection on terminals B and -B. Terminals accepts 0,2÷2,5mm2 (24÷14AWG) wires,
tightening torque 0,5÷0,6Nm. Accumulator should be placed as close as possible to power supply.
Accumulator is protected by fuse F5A inside of PWR. Replacement is possible only by producer or au-
thorized service centre.
Gel type, 12V, Pb accumulators of same age are recommended
It‘ s advised to use external circuit breaker on front of accumulator. Suitable type PC4-HE, DEGSON,
with F3,15A ∅5x20mm fast fuse.
Alarm, s gnal outputs:
Digital outputs and SSR are wired to pluggable terminal.. First terminal switches „Out OK“to „-“(common
terminal with „-“ terminal of output voltage) while supply voltage is in stated levels. Second contact
switches „Batt. Low“ against „-“ common terminal., while voltage on accu. Is too low.
Terminals supports 0,2÷1,5mm2 (24÷16AWG) wires, tightening torque 0,2÷0,25Nm.

Batt. Low: Voltage on accumulator bellow 22V= (only PWR xA 60W 24V)
Operation of the PWR without accumulator
While supply voltage is in stated range (see charts), output voltage level depends on load its function is
presented in output chart. Operator have to Operator must ensure that drawn power don‘ t cross limits
stated in thermal chart.
Operation of PWR with accumulator
In case of loss of power supply PWR will smoothly switch to supply from accumulator. Output voltage is
equal to voltage of the accumulator. Accumulator is permanently disconnected from load in case it is dis-
charged bellow limit. For further operation power supply have to be restored. At same time accumulator
will be charged – charging current is based on other loads to prevent overload of PWR. Maximal charging
current is limited to 0,75A. Output voltage is based on charge level of accumulator (see charts).
Operator have to Operator must ensure that drawn power don‘ t cross limits stated in thermal chart.
This model can be operated also without accumulator. In such a case output voltage will be equal to max-
imal voltage of the output (see specifications).
Operation of PWR from line-to-line voltage in 3~400/230V networks (only PWR 1x xx):
One line is connected to L terminal and other line to N terminal. „In OK“and also „Overvoltage“ LED will be
lit. Operator have to ensure that drawn power follows values defined by voltage and thermal chart
This operation is allowed only in networks with grounded centre TN-C, TN-S, TN-C-S, TT and DC net-
works TN-C (DC) and TN-S (DC). Voltage of any conductor against ground should not exceed 300V~/=.
Operation in isolated networks.:
Operation in isolated networks is generally allowed when line-line voltage don‘ t exceed 300V~.
Operation in 400/230V isolated network is allowed only with insulation monitoring device which dis-
connects network at first failure.
Operation in 690/400V isolated network is prohibited.
Operation of PWR with 3-phase supply voltage(PWR 3x xx)
At least one line have to be live for operation. Operator have to ensure that drawn power follows values
defined by voltage and thermal chart
Other application have to be consulted with producer.
