Now most of the communication equipment has unified specification using 48 v dc power supply. But there are still a few equipment survives 24 v dc power supply. Because of the required current capacity is small, if the rectifier power supply, in order to ensure uninterrupted power supply, must be 24 v battery backup. Apparently neither economy, and take up floor space. Adopt the 48 v and 24 v DC to DC (DC/DC) converter is a suitable way to solve this problem. As shown in figure 24/10 DHY29 - [48] type dc-dc converter principle diagram, the main performance indicators: (1) the input dc voltage nominal value: 48 V allow range: 41 V ~ 51 V (2) the nominal value output dc voltage: 24 V / 10 a voltage regulating range: 21.6 V to 21.6 V (3) the voltage regulation accuracy: + / - 1% or less (4) telephone scale heavy noise voltage noise voltage: 2 or less mv, broadband noise voltage: 20 mv or less (3.4 kHz ~ 30 kHz), fengfeng value noise voltage: 100 mv, or less discrete frequency noise voltage: 5 mv or less (3.4 kHz to 150 kHz) 3 or less mv (150 kHz to 200 kHz) 2 or less mv (200 kHz to 500 kHz) 1 mv or less (0.5 MHz ~ 30 MHz) (5) efficiency: 80% or greater (6) overvoltage, undervoltage, over current protection and current limit values. Overvoltage (29 plus or minus 1) V, undervoltage (21 + / - 1) V, over-current (12 + 1) V current-limiting: 10.5 A ~ 11 A (7) parallel operation of mean flow error: plus or minus 5% or less
