1U Ultra-Compact Embedded DC Power System with 40A Output Current and Hot-Swappable Modular Design for Telecom Power System
1U Ultra-Compact Embedded DC Power System
,40A Output Current Telecom Power System
,Hot-Swappable Modular Rack Mount DC Power Supply
The Vertiv (formerly E merso n) NetSure 212 C23-S1/S2 is an ultra-compact, highly reliable 1U 19-inch embedded DC power system designed for space-constrained telecom access scenarios, including FTTx, OLT equipment, small base stations, fiber access nodes and industrial control applications. It integrates AC distribution, rectification, DC distribution, intelligent monitoring and surge protection in an ultra-thin 1U subrack, delivering stable -48V DC output with a maximum capacity of 40A / 2kW.
Adopting a fully modular, hot-swappable design and front-access maintenance, this system ensures high efficiency, easy deployment and low operational cost. It is the preferred compact power solution for modern access network infrastructure.
- Ultra-compact 1U design: only 44mm height, 19-inch standard rack mount, shallow depth of 290mm — ideal for narrow cabinets.
- Wide AC input range of 80–300VAC, 45–65Hz, with strong adaptability to unstable grids and generator power.
- Supports up to 2 rectifier modules (R48-1000A / R48-500A), system power up to 2kW, max output current 40A.
- Peak rectifier efficiency above 92%, with low power consumption and heat generation.
- Intelligent M225S controller: LCD display, RS232, dry contact, supports remote monitoring and fault alarm.
- Hot-swappable modules: online replacement without system shutdown for high availability.
- Full front operation and maintenance: no rear space required, easy installation and repair.
- Comprehensive surge protection: AC/DC/signal multi-stage lightning protection.
- Wide operating temperature range of -40°C to +65°C for strong environmental adaptability.
- Complete protection: LVBD, OVP, OCP, SCP and OTP to ensure safe operation.
- Dual input versions: S1 (IEC C14 socket) / S2 (3P terminal block) for flexible wiring.
- RoHS compliant and certified: CE, UL, ETSI — global safety compliance.
