Replacement Power for ISR 4331 Routers
PWR-4330-AC is a 250W AC internal power supply for Cisco ISR 4331 routers, and the module is non-hot-swap. The 100-240V AC autoranging input lets an ISR 4331 use standard AC branch power, with a 15A 120V or 10A 240V protected circuit feeding the router. The Cisco ISR 4331 power supply sits inside the chassis, so replacement requires top-cover access, fan-tray removal and system power off. The ISR 4331 has no redundant power supply support. PWR-4330-POE-AC is the PoE sibling for ISR 4331 builds that need endpoint PoE power. Before the PO, confirm ISR4331/K9 and AC input on the chassis label.
PWR-4330-AC price is $322.34. PWR-4330-AC is in stock and available for free next-day delivery. (terms applied)

Technical Details
250W rated output matches the AC power-supply limit of the ISR 4331 chassis. 100-240V AC autoranging input and 47-63 Hz frequency give the circuit range to provision before installation. 3A at 100V AC and 1.3A at 240V AC set the input-current check for low-line and high-line service. PWR-4330-AC is an internal module, and the fan tray comes out before the power supply module is removed. The replacement sequence uses two power supply screws and reconnects the power supply cable connector before the system is turned back on. Normal operation is 0°C to 40°C in the host chassis. The 6-foot electrical power cord ships with AC-powered units. Safety coverage includes UL 60950-1, CAN/CSA C22.2 No. 60950-1, EN 60950-1 and IEC 60950-1.
Ordering
Order PWR-4330-AC as new sealed or certified refurbished for an ISR 4331 AC replacement.

Best For
Failed Router Supply
A failed ISR4331/K9 AC router with Power Supply Module 0 in inventory needs the same 250W AC internal unit. Specify PWR-4330-AC when the chassis label shows ISR 4331 and AC input. Power the router down before replacement and match the non-PoE requirement before the PO.
End-of-Sale Spares
A maintained ISR 4331 fleet past hardware end of sale needs spare power supplies tied to the service window. Cisco stopped selling PWR-4330-AC on November 7, 2023, and Cisco service ends on November 30, 2028. Specify condition, warranty cover and regional sparing location before the PO.
Lab Staging
A staging bench with ISR 4331 AC routers needs the same internal 250W unit used in production hardware. PWR-4330-AC accepts 100-240V AC and is non-redundant. Confirm the lab chassis is non-PoE and schedule downtime for cover removal before the PO.
Not Suitable If
Cisco ISR 4431 routers
PWR-4330-AC fits Cisco ISR 4331 hardware. Cisco ISR 4431 routers use PWR-4430-AC, so a 4431 replacement needs that PID.
PoE switch module power
PWR-4330-AC is the non-PoE AC unit. Cisco ISR 4331 PoE builds use PWR-4330-POE-AC, with 250W endpoint PoE available.
Dual power-supply redundancy
PWR-4330-AC is a single internal Cisco ISR 4331 power supply. Cisco ISR 4331 has no redundant power supply support or dual hot-swap power supply bay.
-48V DC sites
PWR-4330-AC requires 100-240V AC input. DC-input Cisco ISR 4330 replacements use PWR-4330-DC when the chassis label calls for DC power.

Questions & Answers
What is PWR-4330-AC?
PWR-4330-AC is the AC Power Supply for Cisco ISR 4330. It is the 250W AC internal module used in ISR4331/K9 inventory as Power Supply Module 0. PWR-4330-AC= is the spare form, and PWR-4330-AC-RF is the Cisco Refresh form.
What routers does PWR-4330-AC fit?
PWR-4330-AC fits Cisco ISR 4331 routers and the ISR 4330 AC hardware group. It does not fit Cisco ISR 4431 routers; that host takes PWR-4430-AC. Before the PO, confirm ISR4331/K9 and AC input on the chassis label for a replacement.
What power supply does a Cisco ISR 4331 use?
A Cisco ISR 4331 uses PWR-4330-AC for standard AC input and PWR-4330-POE-AC when the build needs PoE power. PWR-4330-AC is the non-PoE 250W AC internal unit. The ISR 4331 has no redundant power supply support.
What are the PWR-4330-AC specs?
PWR-4330-AC is rated at 250W with 100-240V AC autoranging input, 47-63 Hz frequency and 3A to 1.3A maximum input current. It is an internal module for the ISR 4331 chassis. Normal host operation is 0°C to 40°C.
Is PWR-4330-AC hot-swappable?
No, PWR-4330-AC is non-hot-swap in a Cisco ISR 4331 router. Replacement requires system power off, top-cover removal, fan-tray removal and access to the internal power supply module. The ISR 4331 has no second power supply bay for redundancy.
Does PWR-4330-AC provide PoE power?
No, PWR-4330-AC is a Non-PoE power supply. An ISR 4331 build that needs endpoint PoE power uses PWR-4330-POE-AC instead. That PoE power supply gives the Cisco ISR 4331 up to 250W of endpoint PoE power.
What power cord or circuit does PWR-4330-AC use?
PWR-4330-AC is used with AC-powered ISR 4331 routers that ship with a 6-foot electrical power cord. Connect the router to a 15A 120V AC or 10A 240V AC protected circuit. The AC input voltage range is 100-240V AC.
Does PWR-4330-AC work on 120V AC circuits?
Yes, PWR-4330-AC works with 100-240V AC autoranging input, so a 120V AC circuit is within the rated input range. The ISR 4331 AC installation calls for a 15A 120V AC protected circuit. Match the chassis label before ordering.
Can PWR-4330-AC be used for ISR 4331 redundancy?
No, PWR-4330-AC cannot create power redundancy in a Cisco ISR 4331. The ISR 4331 has one internal power supply position and no redundant power supply support. Buyers needing redundant power must use a platform with dual power supply bays.
What is the difference between PWR-4330-AC and PWR-4330-POE-AC?
PWR-4330-AC is the non-PoE 250W AC power supply for ISR 4331 AC hardware. PWR-4330-POE-AC is the ISR 4331 PoE power supply and supplies up to 250W of endpoint PoE power. Choose PWR-4330-AC for non-PoE replacements.
What is the PWR-4330-AC end-of-sale status?
Cisco stopped selling PWR-4330-AC on November 7, 2023. Cisco service ends on November 30, 2028. The Cisco ISR 4331 host has the same last date of support, and there is no Cisco replacement PID for this power supply.
What warranty does ORM provide for PWR-4330-AC?
PWR-4330-AC is sold by ORM as new sealed or certified refurbished. New units carry up to a 3-year extended warranty, and certified refurbished units carry up to 1 year. Certified refurbished units are inspected and bench-tested. Returns are 30 days on every condition; terms apply.
