A-B 1606-XLS480E Central control module

POWER SUPPLY

Ultra-small size

Extra-low inrush current

 Active power factor correction

Wide range AC/DC input; auto select input

Superior reserve power (can support 150% rated power for five seconds)

Superior efficiency and temperature rating

DC-OK and overload LED 
GENERAL DESCRIPTION

The most outstanding features of this 1606-XLS 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 power capability of 150% and built-in large sized output capacitors, these features help start motors, charge capacitors and absorb reverse energy. A wide range input voltage design and a negligible low input inrush current make installation and usage simple. Diagnostics are easy due to the DC-ok relay, a green DC-ok and a red overload LED. Unique quick-connect spring-clamp terminals allow a safe and fast installation. Many global approvals make this unit suitable for nearly every situation.

TERMINOLOGY AND ABBREVIATIONS

PE is the abbreviation for Protective Earth and has the same meaning as the symbol

 This document uses the term “earth” which is the same as the U.S. term “ground”.

To be defined, value or description will follow later. 

A figure displayed with the AC or DC before the value represents a nominal voltage with standard tolerances (usually ±20%) included. 

E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V) As long as not otherwise stated, AC 100V and AC 230V parameters are valid at 50Hz and AC 120V parameters are valid at 60Hz mains frequency. 

A figure with the unit (Vac) at the end is a value without any additional tolerances included.

Safety Extra Low Voltage 

OUTPUT

Power-Boost, short term power capability (up to typ. 4s) 

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-Boost is repeatedly available. Detailed information can be found in chapter 27.1. If the power supply is loaded longer with the Power-Boost than shown in the Power-Boost time diagram (see Fig 8-2), the max. output power is automatically reduced to 480W. If the power requirement is continuously above 480W and the voltage falls below approx. 20V (due to the current regulating mode at overload), the unit shuts-off and makes periodical restart attempts. This behavior is called hiccup mode which is described below. If the voltage is above 20V, the unit continuously delivers current. 

Hiccup Mode:

Up to 4s of overloading, the power supply delivers continuous output current. After this, the output power is reduced to nearly zero for approx. 17s before a new start attempt is automatically performed. If the overload has been cleared, the device will operate normally. If the overload still exists, the output current will be delivered for 2 to 4s (depending on the overload) again followed by a17 s rest time. This cycle is repeated as long as the overload exists. See Fig. 8-3. During the off-period a small rest voltage and rest current is present on the output.
