Only remove equipment when it is disconnected and not in the potentially explosive area. DANGER Components with dangerously high voltage and high stored energy are located in the device! Never carry out work on live parts! Depending on the ambient temperature and the load, the housing can become very hot! CAUTION Before startup please ensure: The mains connection has been carried out by a competent person and protection against electric shock is guaranteed! The device can be disconnected outside the power supply unit in accordance with the regulations as in EN 60950 (e.g. through primary side line protection)! All feed lines are sufficiently protected and dimensioned! All output lines are dimensioned according to the maximum output current of the device or separately protected! Sufficient convection must be guaranteed. ATTENTION: Danger if used improperly The power supply units are built-in devices. The device may only be installed and put into operation by qualified personnel. The corresponding national regulations must be observed.

10 Input

The 12 V DC ... 24 V DC connection is established using the "+" and "-" screw connections. Protection of the primary side The device must be installed in acc. with the regulations as in EN 60950. An internal fuse is provided for device protection. Additional device protection is not required. ATTENTION: Module can become damaged If an internal fuse is triggered, there is a device malfunction. In this case, the device must be inspected in the factory.

11 Output

The connection is established via screw connection terminal blocks "+" and "-" of the DC output. The output voltage can be adjusted on the potentiometer from 30 V DC ... 56 V DC. Protection of the secondary side The device is electronically protected against short circuit and idling. In the event of a malfunction, the output voltage is limited to 60 V DC. Make sure that all output lines are dimensioned according to the maximum output current or are separately protected! The cables on the secondary side should have large cross sections in order to keep the voltage drops on the lines to a minimum. ATTENTION: Module can become damaged Make sure that all output lines are dimensioned according to the maximum output current or are separately protected. The cables on the secondary side must have sufficiently large cross sections in order to keep the voltage drops on the lines as low as possible.

12 Signaling

For function monitoring, there is the active DC OK switching output and the DC OK LED. State 1 State 2 "DC OK" LED ON OFF Active DC OK switching output U OUT (with reference to "–") U = 0 V (in reference to "–") Meaning Normal operation of the power supply unit. UOUT > 0.9 x UN UOUT ≤ 0.9 x UN Secondary load short-circuit or overload No mains voltage or device defective

MINI-PS- 12- 24DC/48DC/0.7 104349_en_00 PHOENIX CONTACT 10 DC OK DC OK+- - Active signal output The DC output signal in normal operation of the power supply unit (UOUT > 0.9 x UN ) is between the "DC OK" and "-" connection terminal blocks and can carry a maximum of 20mA. By switching from "active high" to "low", the DC OK signal output signalizes when the output voltage is fallen short of by more than 10%. The DC OK signal is decoupled from the power output. It is thus not possible for devices connected in parallel to act as an external power supply.

13 Function

-25 IN 20 40 60 Ambient temperature [°C] Output current [A] Thermal behavior The device can supply a nominal output current of 0.7 A with ambient temperatures of up to 60°C. For ambient temperatures above 60°C, the output current must be reduced by 2.5% per Kelvin increase in temperature. From 70°C onwards or in the case of thermal overload, the device reduces the output capacity for its own protection, and returns to normal operation when it has cooled down. Parallel operation Devices of the same type can be connected in parallel to increase both redundancy and power. By default upon delivery, no further adjustments are required. If the output voltage is adjusted, a uniform distribution of power is guaranteed by setting all parallel operated power supply units to exactly the same output voltage. To ensure symmetrical current distribution we recommend that all cable connections from the power supply unit to the busbar are the same length and have the same cross section. Depending on the system, for parallel connection of more than two power supplies a protective circuit should be installed at each individual device output (e.g., decoupling diode, DC fuse or circuit breaker). This prevents high return currents in the event of a secondary device fault.

If a fault occurs in the primary circuit of the first power supply unit, the second device automatically takes over the complete power supply without interruption, and vice versa. For this purpose, the power supply units to be connected in parallel must be large enough that the total current requirements of all loads can be fully met by one power supply unit. External decoupling diodes are required for 100% redundancy (ST 4-QUATTRO-DIO 1N 5408/L-R, Order No. 3037782, ST 4-QUATTRO-DIO 1N 5408/R-L, Order No. 3037795). IN − + IN Σ = 2 xI N Increased performance For n parallel connected devices, the output current can be increased to n x IN. Parallel connection for increasing power is used when extending existing systems. A parallel connection is recommended if the power supply unit does not cover the current consumption of the most powerful load. Otherwise, the load should be divided between individual devices that are independent from one another.
