DPA53 series monitor for ultra-thin (17.5mm) rail mounting type, function: se failure protection, se sequence protection, voltage unbalance protection, adjustable set value undervoltage protection. It is suitable for the protection of the distribution system installed in the cabinet.
I. Overview
DPA53 series three-se relays for three-se or three-se four-ply for the monitor. This series of products measuring their own supply voltage, regenerative voltage, with se sequence protection, lack of protection, undervoltage protection and other functions, N-type products with zero onnection protection. DPA53 series monitor for the ultra-thin (17.5mm) rail mounting type, suitable for installation of the cabinet to install the power distribution system protection, such as: distribution cabinet, distribution box, electric control box, machine tools and other equipment.
Second, the input rated voltage:
200 ~ 240vAC ± 15% (age) Model: DPA53CM23
320 ~ 480VAC ± 15% (age) Model: DPA53CM48
115 ~ 138VAC ± 15% (se voltage) Model: DPA53AM23N
220 ~ 277VAC ± 15% (se voltage) Model: DPA53AM48N
se sequence monitoring: When the three-se power monitor power, such as the se sequence is normal, the relay can pull.
se loss monitoring: When the three-se power monitor power, each se power is normal, the relay can pull.
Undervoltage protection: When the three-se power supply age is lower than the set value, then the relay release protection; when the voltage recovery, the relay back to work properly.
N onnection protection: DPA53AM23N and DPA53AM48N is suitable for three-se four-wer monitor, the two products in the N the relay release.
