VDE-0160 脉冲是一种高能量电压脉冲，可能出现在工业网络的电源电压上（例如在大负载关断时或短路电流衰减后）。

VRLA 电池（英文：Valve Regulated Lead Acid）是阀控密封式铅酸蓄电池，在此类型电池中，由于过充或电池故障而产生的气体可通过安全阀排出。

效率值表示电源的输出功率与输入功率的比值。输入和输出功率之间的差值作为损耗被转化为热量。

经批准用于抑制无线电干扰的电容器，连接在相位与 N 型导体之间或相位之间，并可使差模干扰短路。

经批准用于抑制无线电干扰的电容器，连接在相位与外壳或 PE 之间或者零线与外壳或 PE 之间，并可使共模干扰短路。

A 19-inch rack is a modular system for mounting electronic equipment that complies with the DIN 41494 standard. The system consists of plug-in printed circuit boards (PCBs), PCB mounts (sub-racks) and 19-inch cabinets, all of which are designed to be compatible and to be combined with one another in different ways.

If you want to provide a battery buffer for a 24 V system, you generally use two conventional 12 V batteries connected in series. The batteries must be paired and must have the same state of charge and ageing. If this is not the case, one battery may be overcharged or damaged or may age prematurely. The PULS single-battery concept simplifies this process and extends the useful life of the batteries.

The 3D data are the three-dimensional mechanical designs of the power supplies and devices in electronic form.

Leakage current is also known as stray current or touch current. It is important to limit leakage current in order to protect users from dangerous touch voltage and prevent faults from occurring in the system.

PULS devices can be used without restrictions up to a height of 2000 metres above mean sea level. Above an altitude of 2000 metres, the output power must be derated, because the air pressure falls as the altitude increases. This means that the air becomes less dense, which also reduces the cooling effect of the convection air flow in the power supply.

Ripple and noise voltage is the alternating current voltage superimposed on the output voltage. In the case of a switched-mode power supply, this is specified in mVpp (millivolts peak-to- peak).

A 1-phase power supply with an auto-select or auto-range input detects the input voltage and automatically selects the correct input voltage range.

AWG (American wire gauge) describes the diameter and cross section of wires. The AWG system is mainly used in North America.

Before delivery, PULS subjects every power supply to an endurance test at an increased ambient temperature as part of the manufacturing process. This is known as a burn-in test. The burn-in test is carried out for quality assurance purposes.
