AB 1606-XLE480EP Power Supply 480W 24VDC 20A Single Phase Input

About 1606-XLE480EP :

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

• 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

Typically, a load current is not constant. It varies over time. For pulse load compatibility, following rules must be met:

a) The pulse power demand must be below 150% of the nominal power.

b) The duration of the pulse power must be shorter than the allowed Power-Boost Time. (see output section)

c) The average (R.M.S.) output current must be below the specified continuous output current. If the R.M.S. current is higher, the unit will respond with a thermal shut-down after a while. Use the max. duty cycle curve (Fig. 27-2) to check if the average output current is below the nominal current.

d) For altitudes higher than 2000m reduce the pulse loading (30W/1000m) or the ambient temperature

Instructions:
a) Use appropriate copper cables that are designed for an operating temperature of: 60°C for ambient up to 45°C and 75°C for ambient up to 60°C minimum.
b) Follow national installation codes and installation regulations!
c) Ensure that all strands of a stranded wire enter the terminal connection!
d) Up to two stranded wires with the same cross section are permitted in one connection point (except PE wire).
e) Do not use the unit without PE connection.

1606-XLE120E & 1606-XLE120EC 24V, 5A; Single Phase Input
Instructions for two phase operation:
a) A phase to phase connection is allowed as long as the supplying voltage is below 240V(+10%).
b) Use a fuse or a circuit breaker to protect the N input. The N input is internally not protected and is in this case connected to a hot wire

Adisadvantages:
a. The faulty power supply can not be recognized. The green LED will still be on since it is reverse-powered from the other power supply.
b. It 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 defective unit becomes a load for the other power supplies and the output voltage can not be maintained any more.
