User Manual

Intelbras PSR150-A & PSR150-D Power Supply User Manual

Overview

• The PSR150-A, PSR150-A1, and PSR150-A2 are AC-input and DC-output power modules. The PSR150-D and PSR150-D1 are DC-input and DC-output power modules. These power modules provide an output voltage of 12 V and a maximum output of 150 W.

The PSR150-A2 varies by country and region. For the chassis models available in your country or region, contact the local H3C marketing personnel.

• The PSR150-A, PSR150-A1, and PSR150-A2 AC power modules are similar in views except for their marks. The PSR150-A1 AC power module is used as an example in the following figure. The PSR150-D and PSR150-D1 DC power modules are similar in views except for their marks. The PSR150-D1 DC power module is used as an example in the following figure.

overtemperature protections.
Redundancy| Two power modules can be connected in parallel to achieve 1+1 redundancy and load sharing.
Hot swappable| You can remove one of power modules in 1+1 redundancy while the device is operating. Before removing the power module, disconnect the power module from the external power supply system.
Protection function| PSR150-A, PSR150-D| PSR150-A1, PSR150-A2, PSR150-D1
---|---|---
Protection state| Support for auto- recovery| Protection state| Support for auto-recovery
Output overvoltage protection| The power module is locked and does not supply power.| No| The power module does not supply power.| Automatically restores power supply after the output voltage decreases to an acceptable range

Short-circuit protection

| The power module is locked and does not supply power| No| The power module does not supply power.| Automatically restores power supply after the short circuit condition is resolved
Overcurrent protection| The power module is locked and does not supply power.| No| The power module does not supply power.| Automatically restores power supply after the output current decreases to an acceptable range
Overtemperature protection| The power module does not supply power.| Automatically restores power supply after the temperature decreases to an acceptable range| The power module does not supply power.| Automatically restores power supply after the temperature decreases to an acceptable range

After a power module is locked, it cannot restore power supply automatically after the problems are resolved. Follow this procedure to restore the power module operation:

• Disconnect the power cord from the external power supply system.
• Disconnect the power cord from the power module and then reconnect it.
• Connect the power cord to the external power supply system.

Installing and removing the power module

Safety precautions

• Wear an ESD wrist strap and make sure the wrist strap makes good skin contact.
• Before installing the power module, make sure the operating voltage of the external power supply system is as required by the power module, and the output voltage of the power module is as required by the powered device.
• To avoid bodily injury, do not touch any bare wire or terminal.
• Never place the power module in a wet area and prevent fluid from flowing into the power Module.
• To avoid power module damage, do not open the power module. When the internal circuits or components of the power module fail, contact Intelbras Support.
• Before installing or removing the power module, make sure no power cord is connected to the power module.

Tools
Prepare the following tools for installation and removal  flat-blade screw driver phillips screwdriver and ESD wrist strap.

Installing the power module

• To prevent damage to the power module or the connector on the backplane of the powered device, insert the power module gently.
• If you insert the power module upside down, you will encounter a hard resistance because of the special structure designs of the slot and power module. You need to pull out the power module, orient it correctly, and insert it again.
• If the captive screw cannot be tightly fastened, examine the installation of the power module.

1. Unpack the power module and verify that the input mode of the power module is as required.
2. Remove the filler panel, if any, from the target power module slot.
3. Correctly orient the power module. Grasping the module handle with one hand and supporting the module Bottom with the other, insert the module slowly into the slot along the guide rails.
4. Use a Phillips screwdriver to fasten the captive screws on the power module to secure it in the chassis.

Removing the power module

1. Disconnect the power cord from the power module and the external power supply.
2. Face the front of the power module.
3. Use a Phillips screwdriver to loosen the captive screws on the power module until the captive screws are disengaged from the device.
4. Grasping the handle of the power module with one hand, pull it part way out. Then supporting the power module bottom with the other hand, pull the power module slowly out of the slot along the guide rails.
5. Put the removed power module into an antistatic bag.

Connecting the power cord

Use an AC power cord to connect an AC power module to the external AC power supply system. Use a DC power cord to connect a DC power module to the external DC power supply system.

Connecting an AC power cord

1. Pull the bail latch leftward.
2. Connect one end of the AC power cord to the AC-input power receptacle.
3. Pull the bail latch rightward to secure the power cord plug in place.
4. Connect the other end of the AC power cord to the external AC power supply system.

Connecting a DC power cord

• The power cord color code scheme in the following figure is for illustration only. The cable delivered for your country or region might use a different color scheme. When you connect the power cord, always identify the polarity symbol on its wires.
• Connect the other ends of the wires for the PSR150-D1 power module to a -48 VDC power source, with the negative wire (- or L-) to the negative terminal (-) and the positive wire (+ or M/N) to the positive terminal (+).

1. Correctly orient the DC power cord plug, and insert it into the DC-input power receptacle on the power module.
2. Use a flat-blade screwdriver to fasten the two screws on the DC power cord plug to secure the plug to the DC-input power receptacle.
3. Connect the other end of the DC power cord to the external DC power supply system.

If you insert the DC power cord plug upside down, you will feel hard resistance because of the special structure designs of the DC-input power receptacle and the plug. You need to remove the plug, orient it correctly, and insert it again.
