What are the specifications of a power supply?
Power supply specifications that must be fixed
- Input/output: Input voltage range, output voltage value and accuracy.
- Load: Required current, and presence or absence of transients (including sleep/wake-up of the system)
- Efficiency and standby power.
- Temperature: Maximum/minimum temperatures, and any cooling required.

How do I read my power supply specs?
Look at the “brick” part of the adapter for the word OUTPUT. Here, you’ll see the volts followed by the direct current symbol and then the current. Next, you want to look at your device for the DC input. You’ll usually see at least the voltage near the DC plug receptacle.
What is variable power supply?
A variable power supply is one which includes some means for the user to easily adjust the output voltage and sometimes the current. Adjustment is most often accomplished with a potentiometer, but may also be done with an analog control voltage, a digital input, an autotransformer, etc.
What are the specifications of DC power supply?
DC Power Supply Electrical Specifications
| Item | Specification |
|---|---|
| Maximum output power | 1600 W |
| DC input voltage | Minimum: –40.5 VDC Nominal: –48 VDC Operating range: –40.5 to –72 VDC |
| DC input current rating | 33.3 A @ –48 V nominal operating voltage |
| Internal Supplementary Protector | 40 A |
What is power supply and its types?
There are two types of power supplies existed, AC and DC power supply. Based on the electrical device’s electric specifications it may use AC power or DC power.
Do power supplies need to be calibrated?
Verifying signal integrity specifications is a normal part of calibrating power supplies. On occasion, a calibration reveals an underlying problem that could evolve into a costly failure if left unattended.
Why is ripple and noise considered in power supply specifications?
The ripple and noise parameters are another important power supply specification. It is possible that noise and other impulses on the power line can be transferred to the output of the circuit that is being powered. For linear supplies, ripple frequency is normally be at twice the line frequency.
What is a modular power supply?
Simply put, a modular PSU allows the builder to attach (or detach) cables as they’re needed. Traditional power supplies, on the other hand, have the cables attached permanently to the PSU.
What are the 3 main form factors for power supplies?
Today’s power supply form factors are ATX, ATX12V v1. x, ATX12V v2. x, and micro-ATX.
