ER4850/S Rectifier User Manual

1 Brief Introduction

1.1 Model Description

The model of ER4850/S rectifier (rectifier for short) is described in

Figure 1.

1.2 Appearance

The appearance of the rectifier is shown in Figure 2.

1.3 Front Panel

The rectifier provides one triangle button and three indicators on the

front panel, as shown in Figure 3.

Triangle button

Function of the triangle button:

The rectifier is fixed in the cabinet through a handle. Pressing the

triangle button, and the snap of the handle locks the rectifier into the

cabinet; pressing the triangle button again, and the handle pops out to

unlock the rectifier from the cabinet, then the rectifier can be pulled out.

The functions of the indicators are described in Table 1.

1.4 Back Panel

The rectifier provides an AC input socket and a DC output socket on the

back panel, as shown in Figure 4.

2 Functions

Protection

The rectifier provides the following protection functions: input

overvoltage and undervoltage protection, output overvoltage protection,

fan fault protection, short circuit protection and overtemperature

protection.

Fault display

The rectifier faults are indicated by the states (on, off and blinking) of the

indicators on the front panel. For the fault information and treatments,

refer to Table 4.

Fan speed control

The fan has stepless speed regulation control. The fan speed is

1

regulated and controlled according to the output current and the ambient

temperature of the rectifier.

Communication

The rectifier communicates with the main controller in CAN mode. It

sends its output voltage, current, protection and alarm information to the

main controller. The detailed communication functions include remote

acquisition of alarm, digital and analog signals, remote control and

remote adjustment of voltage analog signal.

3 Installation And Use

Installation

Figure 5 shows the installation dimensions of the rectifier. Install the

rectifier into the cabinet, and ensure that the input and output sockets

have been connected to the cabinet reliably. Press the triangle button to

ensure that the rectifier and the cabinet are fixed together. The

relationship of the snap and the cabinet or subrack is shown in Figure 6.

Heat dissipation

The rectifier uses intelligent air-cooled mode. The fan is installed in front

of the rectifier and blows the air from front to back. Therefore, Make sure

that the air intake and air outlet of the rectifier are not obstructed during

arranging the rectifier position.

Hot-plug

The rectifier provides hot-pluggable function. It is prohibited to plug and

unplug the rectifier with power-on in flammable environment!
