CHARGER-INVERTER (Studer Xtender XTM) 24V/230V 90A 3500VA

Form

Combined pure sine wave inverter, multi-stage battery charger, and automatic AC transfer switch mechanism from the Xtender series. Features a robust metal housing with forced ventilation.

  • protection: IP20.
  • acoustic level: < 40 dB without ventilation, and < 45 dB with forced ventilation starting from 55°C.
  • thermo-sensitivity: operating temperature ranges from -20°C to +55°C.
  • certifications: compliant with Low Voltage Directive (LVD) 2014/35/EU and Electromagnetic Compliance (EMC) Directive 2014/30/EU.
  • dimensions (H x W x L): 133 x 322 x 466 mm.
  • weight: 21.2 kg.

Per piece.

Fit

Interfaces & Compatibility:

  • battery voltage (DC interface): 24 V DC nominal, with an input range of 19–34 V DC.
  • AC input (grid/generator interface): 150 to 265 V AC or 50 to 140 V AC, at 45 to 65 Hz.
  • transfer relay & output limits: maximum input current of 50 A AC, and maximum output current of 56 A AC.
  • optional interfaces: compatible with the arm 02 module (2 multifunction contacts) and the rcm 10 module (1 remote entry).
  • temperature compensation: interfaces with BTS 01 or BSP 500/1200 accessories.

Function

Primary function:

  • functions as a pure sine wave inverter, automatic battery charger, and AC transfer switch to reliably supply AC loads and manage energy storage; specifically designed for use in off-grid, backup, and hybrid energy systems.

Electrical Ratings & Performance:

  • AC output: produces a pure sine wave at 230 V AC (± 2%) or 120 V AC, 45-65 Hz ± 0.05% (crystal controlled).
  • continuous power: 3000 VA at 25°C.
  • 30-minute power: 3500 VA at 25°C.
  • 5-second surge power: 9 kVA at 25°C.
  • maximum efficiency: 94% for the 24Vdc system.
  • battery charger: provides a maximum charging current of 90 A; uses a 6-step charge characteristic (bulk, absorption, floating, equalization, reduced floating, periodic absorption) with power factor correction (PFC).
  • standby & load detection: consumption is 1.4 W OFF / 1.6 W Standby / 12 W ON, with adjustable load detection (standby) from 2 to 25 W.
  • transfer time: < 15 ms.

Environment:

  • humidity: operational at 95% relative humidity without condensation.

Limitations & Protections:

  • overload and short-circuit: features automatic disconnection with 3 restart attempts.
  • overheating: features an acoustic warning before shut-off, followed by an automatic restart.
  • asymmetrical loads: capable of handling asymmetric loads up to the continuous power rating (Pcont).
  • battery voltage warning: strictly requires a 24 V DC battery bank; it is not interchangeable with 12 V (XTM 2000-12) or 48 V (XTM 4000-48) variants.
