1336-PB-SP2B Driver Power Board Introduction

1336-PB-SP2B is a pre charging power board specifically designed for Allen Bradley 1336 series frequency converters. It is mainly used to control the charging of bus capacitors and ensure the safe start-up of the frequency converter. The following is a detailed introduction:

Belonging to the 1336 series inverter dedicated pre charging control power board

Suitable for 460V voltage level, 60-600HP medium and high power models

Compatible with 1336 PLUS, PLUS II, FORCE, IMPACT, REGEN series

Core function: Limit surge current during power on, protect rectifier bridge and bus capacitor

Automatically switch to the main circuit after completing pre charging to ensure normal operation

Integrated voltage sampling, relay drive, and state feedback circuit

Onboard LED indicator light, displaying pre charging status and fault information

Equipped with multiple protections for overcharging timeout, bus overvoltage, and undervoltage

Common fault codes: F11 pre charging fault, F22 bus undervoltage

The common fault phenomena are power on failure, resistance heating and burning, and inability to establish voltage

Vulnerable components: pre charging resistor, driving relay, sampling circuit components

The original factory has ceased production, and the market is dominated by second-hand, refurbished, and inventory spare parts

Different in voltage and power from models such as SP22B and SP23B, they cannot be directly interchanged

Disassembly and assembly must be powered off and discharged for at least 10 minutes, and anti-static measures must be taken

Repair suggestion: ｒｅｐｌａｃｅ the entire board directly, which can be upgraded to the PowerFlex series in the long term

In summary, 1336-PB-SP2B is a key component for the electrical safety of 1336 frequency converters. Understanding its functions and fault characteristics can quickly identify problems and complete spare parts replacement.
