  • All Catalyst 4500 E-series AC-input power supplies require single-phase source AC.
  • All AC power supply inputs are fully isolated.
  • Source AC can be out of phase between multiple power supplies in the same chassis, which means that PS1 can be operating from phase A and PS2 can be operating from phase B.
  • For high-line operation, the power supply operates with the hot conductor wired to a source AC phase and the neutral conductor wired either to ground or to another source AC phase as long as the net input voltage is in the range of 170 to 264 VAC.
  • Source AC can be out of phase between AC inputs on power supplies that are equipped with multiple AC inputs, which means that power cord 1 can be plugged into phase A and power cord 2 can be plugged into phase B

About New Bulk Pack Products

New Bulk Pack products come with clamshell boxes and do not have any manufacturer warranty. Many times manufacturers disassemble whole units to use parts or pulled from a new system. Typically, this product doesn't come with software or instructions unless indicated and no Manufacturer’s genuine warranty. You can take note these are not brand new products.

Switching power supplies are not new inventions, first used in the 1970s. Today, they form the bulk of power supplies in the market for industrial and consumer use. As technology advances, the need for more efficient power supplies increases. The formerly famous linear power supplies cannot keep up with the new requirements, leading to the rise of switch-mode power supplies.

Efficient Thermal Management System

Power supplies generate a lot of heat in the conversion process. Not all the input AC power is converted to output DC power. The rest is lost in the form of heat, which increases the temperature inside a power supply. The switching power supplies have better thermal management, which prevents excess heating. So, they can perform well in many industrial applications.

High Efficiency

One of the reasons leading to the rise of switch mode power supply is the high efficiency. Apart from having an efficient thermal management system, the power conversion frequency is above 90%. With this high rate, you don't have to worry about power wastage even if the SMPs remain in constant operation. The saved power may not be significant for home applications, but industrial users can feel the relief on their utility bills.

Low-Cost and Long Service Life

Most of the electronic components in power supplies degrade at high temperatures. A switching power supply maintains optimal thermal conditions even if used continuously. This reduces the operating cost and lengthens the lifespan of the entire power supply unit. We can also say that you get a more reliable power supply that is not prone to hardware failure.

Low Weight and Ultimate Protection

The use of switching elements in a switch mode power supply reduces the weight of the entire unit. The size of the required transformer is also reduced. This property is ideal if manufacturing or shopping for a power supply for your portable device. These power supplies also show excellent protection properties. The protection circuitry offers short-circuit, overload, overvoltage, overcurrent, and overheating protection. They are safe for use under any conditions.

Power Factor Correction Mechanism

The ability of a switching power supply to correct power factor is on another level. The harmonics your equipment feeds back to a power system can see the authorities increasing your utility bills. Using switching power supplies takes you off the hook as the PF will always be within the permitted value.

What to Know When Shopping for a New Power Supply?

Busying a switch-mode power supply presents a challenge to many people. That is probably because of the many models and form factors available in the market today. To get it right, understand the power requirement of your system and the form factor of the power supply that will fit in the casing. You should not have any problems if you consider the power factor model.
