PSU100D - Low-cost power supply for wall mounting
The attractively priced PSU100D regulated power supplies can be screwed directly onto the wall. The rugged aluminum enclosure with IP20 degree of protection can be variably mounted in different positions, even in applications with high temperatures and high shock and vibration requirements. The wide-range input enables connectivity to the most diverse supply networks worldwide and ensures reliable 12 V or 24 V supply even if there are large voltage fluctuations.
SITOP PSU100P 24 V/ 5 A and 8 A
Rugged 1-phase power supply with IP67
The SITOP PSU100P power supplies for wall mounting with their rugged design in IP 67 class of protection are ideal for distributed applications outside the control cabinet. The automatic switching of the input voltage of 1-phase devices and the temperature range of -25° to +60°C means they can be used worldwide. The high efficiency of up to 93% keeps the heat development and the inherent energy consumption low. The operation indicator on the unit uses LEDs (green = "24 V DC OK", flashing red = overload). A floating signal contact provides the status of the output voltage and enables easy system integration.
SITOP PSU300B 12 V/ 20 A, 24 V/ 17 A and 24 V/ 30 A for battery charging
The power supplies are optimally suited for battery charging because of their constant-current characteristic. For other applications the output characteristic can also be switched to latched shutdown. The three-phase wide-range input allows world-wide deployment. The compact design takes up little space on the mounting rail and requires no gaps for mounting.
Three-phase power supply SITOP PSU300E 24 V/ 5 A
Sturdy metal enclosure is only 42 mm wide and does not require mounting distances on the sides to other devices
Low heat generation due to the high efficiency level of 90%.
The wide input range of 320 V to 550 V 3AC allows for mains buffering times of 50 ms, thus enabling use in unstable threephase systems
Removable plug-in terminals simplify the connection to AC and DC.
An LED and an integrated “DC 24 V OK” signaling contact indicate the status of the output voltage.
Output voltage can be adjusted from 24 V to 29 V.
Wide temperature range from 0 to +60 °C
DC/DC converter 12 V/ 2.5 A
The narrow rail-mounted device supplies 12 V/ 2.5 A and is connected to 24 V DC, e.g. to the output of a SITOP power supply unit. With an additional SITOP DC UPS, uninterruptible 12 V direct voltage can also be generated.
DC/DC converters 24 V/2 A
With an input range from 16.8 V to 138 V DC for supply 24 DC from battery and DC systems.
Unlimited diversity thanks to variable output
The innovative circuiting concept offers flexible setting of the output voltage betweeen 3 and 52 V. This means special voltages can also be handled reliably by a standard device.
Electrical powering of the switching cabinet
The industrial, DIN rail device has two 15 V outputs. For electronic devices, for instance, which are powered with ±15 Volt.
The compact metal housing of the power supplies 24 V/5 A and 10 A can be accommodated where only limited installation depth is available, even in masked machine supporting frames or hinged frames.
30 V power supply units for the AS-Interface
The power supply units supply the AS-i network and the connected slaves from a central point. They are an integral part of an AS-i network and, in conjunction with the data decoupling, enable the simultaneous transmission of data and energy on the same two-wire cable.
