Superior 3-Stage Data Line Surge Protection Circuit
Standards: UL 1449 3hd edition, IEC 61643:1998, NEMA LS1.
The DLP H series provides superior surge protection for data and signal line applications. Using higher capacity components, these units offer an improved level of reliability than other similarly priced products. To cover a broader range of applications, four different styles of protection circuits and ten standard voltages are offered to fine tune the protection to your equipment.
Category A Local Panel SPD:
We offer AC Power Line Protection of good quality. PT40-Family Surge Protective Device For Installation at branch and local panels. These specifications describe the electrical and mechanical requirements for a shunt installed AC power line surge suppressor. The specified surge protective device shall provide effective energy surge diversion for application in ANSI/ IEEE C62.41-2002 Location Category B3 environments. Testing per ANSI/ IEEE C62.45-2002 using ANSI/ IEEE C62.41 Category B3 waveforms and amplitudes. UL 1449 listed to UL1449 3rd Ed Safety Standard for Surge Protective Devices.
The specified surge protective device shall provide:
The term SURGE is used to describe a transient over voltage on a power line that has duration of a few μ secs. A transient over voltage can exceed the insulation rating of the electrical equipment causing degradation of insulation and immediate damage to the equipment. Relatively low amplitude transient over voltage applied repetitively on the equipment will reduce its mean time before failure. The result will be that equipment will have to repaired more often, waste production time, increasing operating cost.
The three main types of damage are:
Transient over voltages are generated:
Hence, it is very important to protect the sensitive electrical and electronic equipments against these transient voltage surges.
The transient voltage surges are broadly classified into two types i.e.:
The lightning surges bring very high amount of destructive energy into the system and hence, are potentially very dangerous. The Class B SPDs are designed to handle the Lightning current surges.
The switching surges are relatively frequent than the Lightning surges. Although they bring in relatively less energy into the system, but however, still strong enough to damage the sensitive electronics. The switching surges are handled by the Class C SPDs.
In addition, Class D (Type III) Surge protectors are installed near to the sensitive / critical equipments. The Class D SPDs are meant to protect sensitive electronic equipments like measuring and control devices, critical instrumentation, signalling, etc. The residual voltage in these protectors is very low and is compatible with the respective electrical and electronic equipments connected. These are available for 230V AC and 7.5, 18, 60, 90, 240, DC applications.
The salient features of the MSPD system are:
Combined (Class B & C) protection – This enables protection against both lightning and switching surges originating from outside our power system to be isolated at the main incomer level itself.
Status indicator flag (local indication) – Since any SPD for the power supply line is always connected in parallel to the circuit, the status indication is very essential.
Potential free contacts for Remote indication – In addition to a local indicator flag, the MSPD also offers potential free contacts using which any form of audio visual alarm/ automation can be configured.
