AB 1606-XLS480E-3 480 W 24V DC No Special Function Performance Family 3-Phase
About 1606-XLS480E-3 :
The most outstanding features of this 1606-XLS DIN-rail power supply are the high efficiency and the small size, which are achieved by a synchronous rectification and further novel design details.
With short-term peak power capability of 150% and built-in large sized output capacitors, these features help start motors, charge capacitors and absorb reverse energy and often allow a unit of a lower wattage class to be used. High immunity to transients and power surges as well as low electromagnetic emission makes usage in nearly every environment possible. The integrated output power manager, a wide range input voltage design and virtually no input inrush current make installation and usage simple. Diagnostics are easy due to the dry DC-ok contact, a green DC-ok LED and red overload LED. Unique quick-connect spring-clamp terminals allow a safe and fast installation and a large international approval package for a variety of applications makes this unit suitable for nearly every situation
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. The Power-Boost is repeatedly available. Detailed information can be found in chapter 27.1 . Once Power-Boost has been stopped by the output power limiter, a timer disables the next Power-Boost capability. The recovery timer will start as soon as the output voltage reaches the adjusted value again, which usually happens after the load has been reduced.
Power supplies can be paralleled for redundancy to gain a higher system availability. Redundant systems require a certain amount of extra power to support the load in case one power supply unit fails. The simplest way is to put two XLS power supplies in parallel. This is called a 1+1 redundancy. In case one power supply unit fails, the other one is automatically able to support the load current without any interruption. Redundant systems for a higher power demand are usually built in a N+1 method. E.g. Five power supplies, each rated for 10A are paralleled to build a 40A redundant system.
Please note:
This simple way to build a redundant system does not cover failures such as an internal short circuit in the secondary side of the power supply. In such a
- virtually nearly impossible
- case, the defect unit becomes a load for the other power supplies and the output voltage can not be maintained any more. This can only be avoided by utilizing decoupling diodes which are included in the redundancy module 1606-XLSRED. (One module per power supply)
Recommendations for building redundant power systems:
a) Use separate input fuses for each power supply.
b) Monitor the individual power supply units. A DC-ok lamp and a DC-ok contact is already included in the units This feature reports a faulty unit.
c) When possible, connect each power supply to different phases or circuits
d) It is desirable to set the output voltages of all power supplies to the same value to avoid a false DC-ok signal.
1606-XLE120E & 1606-XLE120EC 24V, 5A; Single Phase Input
Above an average output current of 2.7A, the harmonic current standard EN61000-3-2 is not fulfilled.
Please note:
A power supply has to comply with EN 61000-3-2 (Standard for harmonic input current) when:
1) the end-device is used within the European Union and
2) the end-device is connected to a public mains supply with a nominal voltage ≥ 220Vac and
3) the power supply is:
- fitted in an end-device with an average input power in excess of 75W or
- fitted in an end-device with a continuous input power in excess of 75W or
- part of a lighting system.
